Does anybody know how to start writting your own constitutive model based on tests that you've done in lab (triaxial test and oedometer test).
Is there some procedure that you have to stick by.

SP-265-15 Structural Concrete Beam Shear - Still a Riddle ?
Synopsis: The paper reviews the application of classical plasticity theory to shear
failure of structural concrete beams. The resistance of concrete to shearing deforma-
tions is described by the modified Coulomb failure criterion. For beams with shear
reinforcement, this leads to an upper bound solution based on yield lines minimizing
the combined work of yielding stirrups and cracking concrete, the coinciding lower
bound solution corresponding to an inclined compression field (the web-crushing
criterion). For beams without shear reinforcement, the optimal failure mechanism is
a single yield line (straight or hyperbolic) from load to support, the coinciding lower
bound solution corresponding to a compressive strut between the load and support
platens. The predicted failure mechanisms and ultimate loads are compared with
experimental evidence, and it is concluded that the plasticity approach goes a long
way toward solving the riddle of shear failure.

Review
Praise for Einar Bardal's, Corrosion and protecction
Choice
"The style is direct and the explanations easily followed. The theoretical material is not ove4rwhelming but is adequate of a strong foundation. Many clear and affective figures and diagrams are included. The book is recommended for introductory courses in corrosion and as a practical reference for practicing engineers and technicians who want a clear description o basic principles and applications."
Product Description
Corrosion and Prevention is an essential guide for mechanical, marine and civil engineering students and also provides a valuable reference for practicing engineers. Bardal combines a description of practical corrosion processes and problems with a theoretical explanation of the various types and forms of corrosion, with a central emphasis on the connections between practical problems and basic scientific principles. This well thought-out introduction to corrosion science, with excellent examples and useful tables, is also extremely well illustrated with 167 diagrams and photographs. Readers with a limited background in chemistry can also find it accessible.

Contents of the package:
1. BS 1722-1:2006 Fences. Specification for chain link fences
BS 1722-1 specifies requirements for chain link fences, gates and gateposts for use with chain link fences. The gates specified are steel with a provision for chain link infill or other infill if required by the purchaser.
2. BS 1722-2:2006 Fences. Specification for strained wire and wire mesh netting fences
3. BS 1722-5:2006 Fences. Specification for close-boarded fences and wooden palisade fences
4. BS 1722-7:2006 Fences. Specification for wooden post and rail fences
5. BS 1722-8:2006 Fences. Specification for mild steel (low carbon steel) continuous bar fences and hurdles
BS 1722-8 provides requirements for mild steel (low carbon steel) continuous bar fences for farm animal containment applications and welded hurdle fences of continuous bar type.
6. BS 1722-9:2006 Fences. Specification for mild steel (low carbon steel) fences with round or square verticals and flat horizontals
This British Standard, a part of the BS 1722 series, specifies requirements for self adjusting (nibbed) or welded mild steel (low carbon steel) fences with round or square verticals and rolled hollow section (RHS) or rolled steel joist (RSJ) posts and flat horizontals. It also specifies requirements for their installation.
This British Standard covers requirements for protective treatment. However, maintenance of the fence after installation is outside the scope of this standard.
This standard aims to establish minimum requirements for materials and workmanship of the more common types of fence in order to ensure satisfactory service for the purchaser, and to assist manufacturers and installers by eliminating unnecessary minor variations in the demands of purchasers. It specifies requirements for the components that make up a fence and the way in which the fence needs to be constructed. The standard includes requirements for sizes of components, together with the permissible tolerances on size.
The major changes in this revision are the removal of flat posts from the standard, the inclusion of RHS posts, removal of requirements for angle corner posts, which in this edition are specified as for line posts, and revision of the requirements for gates. The opportunity has also been taken to simplify the construction and installation requirements in line with current practice.
BS 1722-9 specifies requirements for self-adjusting (nibbed) or welded mild steel (low carbon steel) fences with round or square verticals and rolled hollow section (RHS) or rolled steel joist (RSJ) posts and flat horizontals. It also specifies their requirements for installation.
7. BS 1722-10:2006 Fences. Specification for anti-intruder fences in chain link and welded mesh
This part of BS 1722 specifies requirements for anti-intruder chain link or welded mesh fences and gates of at least 2.4 m in height for situations that require a higher level of protection than that offered by fences conforming to BS 1722-1. This British Standard also covers requirements for the installation of the fencing at the specified location. Provision is made for either single or double extension arms.
The aim of this standard is to establish minimum requirements for material and workmanship of the more common types of fence in order to ensure satisfactory service for the purchaser, and to assist manufacturers and erecting contractors by eliminating unnecessary minor variations in the demands of purchasers.
The specification given in this standard is suitable for use in industrial estates, airfields, oil and gas installation etc.
This revision of BS 1722-10 provides a more detailed specification for gates and locking devices. Further changes in this revision include clarification of the specification for posts and the use of heavier gate posts to act as fence strainers. The thickness of stirrup wire has been lowered to facilitate fixing of the mesh. Cube tests of concrete strength are now required and the frequency of testing is specified to ensure that regular quality checks are made.
8. BS 1722-11:2006 Fences. Specification for prefabricated wood panel fences
BS 1722-11 details requirements for the materials, design, construction and installation of prefabricated wood panel fences constructed from softwood panels, fixed between timber or concrete posts. This standard does not cover fences of a height greater than 2 m above ground level.
9. BS 1722-12:2006 Fences. Specification for steel palisade fences
This British Standard, a part of the BS 1722 series, specifies requirements for steel palisade fences and gates for general purposes (GP) in corrugated and angle pales for heights up to 2.4 m and for security (SP) purposes in corrugated pales for heights of 3.0 m and 3.6 m, all with posts at 2.75 m centres. This standard also covers fences between 2.4 m and 3.0 m in height with components constructed to the SP specification.
This standard specifies requirements for fence materials and their combination and installation.
In situations of extreme exposure or abnormal loading it will be necessary to carry out a special appraisal and for the design criteria to be specified.
10. BS 1722-14:2006 Fences. Specification for open mesh steel panel fences
BS 1722-14 specifies requirements for the following categories of open mesh steel panel fences:
Category 1: General purpose fences up to 2.4 m high;
Category 2: Security fences at least 2.4 m high;
Category 3: High security fences at least 3.0 m high;
Category 4: Extra high security fences at least 3.0 mm high.
Requirements for the performance of panel fences for this standard are based upon loadings.
The principal changes introduced in this edition are to bring the requirements up to date with other parts of BS 1722 and to accommodate changes in cross references to other standards. This edition also introduces requirements for very high security fences and for concrete posts for fences.
11. BS 1722-16:2009 Fences. Specification for powder coatings used as a plastics finish to components and mesh
Dear friends, if someone of you have the missing standards from this standard series, please share it.

The book is much more than a mere list of uses of the metals and metallic minerals, which historically and contemporarily occupy a very important place in the civilization of human race and in the day-to-day human life. Uses of metals have been projected along with their backward linkages with history, recovery from minerals and particular sets of physical/chemical characteristics and with their forward linkages with the status and trends in waste utilization and substitution wherever relevant. Apart from extraction of metals, the direct industrial uses of the metallic minerals and the specifications with emphasis on the principles and reasons have also been discussed. In this book, the 12 metallic minerals, 29 metals and 6 metalloids that are important in today?s economy, have been brought within one cover. Some of the information incorporated in it are not ordinarily accessible to many, but have been obtained by the author through personal contacts with the industries during the last 35 years. The book presents a highly technical subject in an easily understandable logical fashion.

The present proceedings are numbered Vols. 3 and 4 because they form an integral part of the entire series. It contains three overview papers on laboratory testing, in-situ testing, and characterisation of natural soil variability. Less well documented soil types such as organic clays and peats, loess, volcanic soils, residual soils, methane hydrate soils, and recent sediments are covered by fifteen papers. The remaining papers cover: alluvial and marine clays (6), highly fissured clays (1), boulder clay (1), silts (1), and natural soil variability (4). Following the tradition of the first workshop, authors were invited under consultation with the advisory committee chaired by Dr David Hight. The length and quality of the papers speak volumes on the tremendous dedication and efforts invested by all the invited authors. It is worth reiterating that the major part of the credit for this entire series belongs to the authors.
