Author: Anatoly A. Komarovsky; Viktor P. Astakhov, | Size: 12.9 MB | Format:PDF | Publisher: CRC Press LLC | Year: 2003 | pages: 629 | ISBN: 9780849311512
Features
Presents a breakthrough approach in the mechanics of solids that leads to a fundamental understanding of the relationship between materials structure, processing, and properties
Theoretically formulates and experimentally proves new concepts for controlling deformation and fractures
Derives the thermodynamic equation of state of solids and uses it to propose new theoretical and practical concepts, methods, and design techniques
Shows that the equation of state can explain all phenomena and effects related to deformation and fracture processes and will lead to new methods for predicting and controlling material operating properties
Summary
Still passive and for the most part uncontrollable, current systems intended to ensure the reliability and durability of engineering structures are still in their developmental infancy. They cannot make corrections or recondition materials, and most material and structural failures cannot be predicted. Accidents-and catastrophes-result.
Physics of Strength and Fracture Control: Adaptation of Engineering Materials and Structures introduces a new physical concept in the science of the resistance of materials to external effects, a concept that opens completely new avenues for improving the strength and safety of engineered objects. Based on a thermodynamic equation of state of solids derived by the author, the approach provides a general methodology for treating all the physical and mechanical properties of materials, regardless of their nature and physical state. The author shows that this approach enables the control of the stressed-deformed state both to prevent failures and fractures and to promote them for easier shaping of materials. He uses this methodology to present and discuss non-traditional but practical ways of solving real-world problems.
Of enormous theoretical and practical significance, this groundbreaking work ushers in a new stage in the science of material strength. It opens the door to systematic ways to design materials, control their operating properties, and predict their behavior under specific operating conditions.

Water and wastewater treatment plant operators must have a breadth of knowledge that encompasses more than scientific theory. With two new chapters and more than 300 new practice scenarios, this second edition continues to offer a complete resource exclusively for water and wastewater plant operators. It is a thorough compilation of water science, treatment information, process control procedures, problem-solving techniques, safety and health information, and administrative and technological trends. The manual examines numerous real-world operating scenarios, including the intake of raw sewage and the treatment of water via residual management. Each scenario includes a comprehensive problem-solving practice set.

Best Practice Guidance for Hybrid Concrete Construction
Author: C. H. Goodchild, J. Glass | Size: 1.7 MB | Format:PDF | Publisher: The Concrete Centre | Year: 2004 | pages: 64 | ISBN: 1-904818-09-9
Hybrid Concrete Construction (HCC) is about providing best value in structural frames.
HCC provides simple, buildable and competitive structures that answer client demands
for better value. It meets industry requirements for increased prefabrication, increased
off-site activity, safer and faster construction and consistent performance.
Despite the challenges thrown down by the Latham2 and Egan3 reports and their
successors, the UK has been slow to realise the benefits of HCC. One of the barriers to
HCC’s more widespread use was found to be the lack of comprehensive guidance, a
situation which this publication aims to change.
Based upon work carried out under a PII research project, this publication demonstrates
how to achieve best practice. The guidance explains the benefits that result from:
■ early involvement of specialist contractors
■ using a lead frame contractor
■ using best value philosophy
■ holding planned workshops
■ measuring performance
■ trust
■ close co-operation – with an emphasis on partnering.
The guidance is supported by case studies and shows that although there are intense
periods of co-ordination during the design phase, there are tremendous rewards on site
and in use. Best value is achieved through communication and measured in terms of
buildability, construction speed, aesthetic, quality, environmental and whole-life cost
benefits.
HCC can achieve very significant cost savings and give rise to some very satisfied
clients. This publication is intended to show how this can be achieved.

This Standard specifies methods by which a test piece of metal is strained in uni-axial
tension at room temperature in order to determine one or more of its tensile properties. It
defines the properties to be determined and the terms used in describing tests and test
pieces. The Standard also specifies the dimensions of standard test pieces and methods for
tensile testing a wide range of product forms.
Where material Standards (product Standards) specify the dimensions of the test piece,
those dimensions take precedence over the dimensions which are specified in Appendices A
and C.

The enormous advantages of sprayed concrete as a construction process
and the improvement of equipment, materials and application know-how have made it an important tool for various types of work.
Sprayed concrete takes care of stability problems in tunnels and other underground constructions. Today sprayed concrete is a key factor for rock support in
< Tunnelling
< Mining operations
< Hydropower projects
< Slope stabilization
More than 90 % of all sprayed concrete is used for rock support.
In comparison with traditional concrete, sprayed concrete is used today to a relatively small extent, but when it is used, it is done so in many different
ways. Some examples:
< Pit curbing
< Canal lining
< Reconstruction and repair
< Sea walls
< Refractory
< Fire and corrosion protection
< Spraying of new constructions
< Agriculture (manure pits)
< Plastering and stabilizing of brick walls
Sprayed concrete is the building method of the future due to
< Flexibility
< Rapidity
< Economy
