Fracture Resistance Testing of Monolithic and Composite Brittle Materials
Fracture Resistance Testing of Monolithic and Composite Brittle Materials
(ASTM Special Technical Publication, 1409)
ASTM International; illustrated edition (January 1, 2002) | English | 0803128800 | 237 pages | PDF | 4.31 MB
STP 1409 features 14 peer-reviewed papers that summarize the latest methods for the measurement of fracture toughness, slow crack growth, and biaxial strength. It also identifies new areas for fracture toughness test methods development and standardization, such as testing of complex materials, elevated temperature measurement, and R-curve measurement.
5 sections cover:
· Plenary Session – discusses 30 years of progress in fracture mechanics of brittle materials.
· Implications For Design and Testing – focuses on the analysis of plates for biaxial strength testing and the transition in measured fracture toughness from a value associated with the properties of a single grain to the polycrystalline value.
· Fracture Toughness Standardization – examines 3 techniques that were developed and standardized as part of ASTM C 1421 Standard Test Methods for Determination of Fracture Toughness of Advanced Ceramics at Ambient Temperatures. These techniques show convergence when good metrology is employed. In addition to standardized techniques, this section discusses the single edged V-notched beam method that is on a fast track for standardization in Europe.
· Crack Growth Resistance – covers testing of functionally graded materials, elevated temperature R-curve testing, and the study of a toughening mechanism. Although most researchers applied classical mechanical techniques for the measurement of fracture toughness or crack growth resistance, both theoretical and fractographic methods were also presented.
· Unique Materials and Environmental Effects – examines elevated temperature fracture toughness testing of particulate reinforced ceramic composites, thermal and environmental effects on the fracture toughness of titanium carbonitrides for machining, and environmental interactions that lead to rate effects in "dynamic fatigue" (i.e., stress corrosion) testing.

Geosynthetics in Civil Engineering
Publisher: Woodhead | Pages: 312 | 2006-12-22 | ISBN 1855736071 | PDF | 6 MB
Building a strong foundation in the fundamentals of geosynthesis, Geosynthetics for Civil Engineering discusses the design and durability of geosynthetics together with their material properties and the international standards governing their use. The book examines the various applications of geosynthetics in areas such as filters, separators, landfills, barriers, and foundation materials. It covers design concepts, manufacturing, costs, the use of different natural and synthetic materials, methods of quality assurance, and the service life of geosynthetics. Written by an international team of contributors, the book is ideal for civil engineers and producers of geosynthetics.

behavior of long links in eccentrically braced frames
The Earthquake Engineering Online Archive
Behavior of long links in eccentrically braced frames
Engelhardt, Michael D.; Popov, Egor P.
UCB/EERC-89/01, Earthquake Engineering Research Center, University of California, Berkeley, 1989-01, 406 pages (510/E532/1989)
This report describes an experimental investigation and associated studies of the behavior of long, flexural yielding links in seismic-resistant eccentrically braced frames (EBFs). EBFs provide ductile behavior under severe earthquake loads by restricting yielding to beam segments called "links." The central focus of this report is an experimental investigation of 14 2/3-scale subassemblages subjected to cyclic loads. The subassemblages model a portion of a single-diagonal EBF with the links attached to the columns. Based on the findings of this investigation, combined with the results of previous EBF research, preliminary design recommendations are provided for the use of long links not attached to columns. Included are recommendations on the design yield strength, ultimate strength, plastic rotation capacity, and stiffening requirements for long links. The suitability of brace-to-link connection details for use in EBFs with long or short links is also demonstrated.

Computational and Experimental Mechanics of Advanced Materials
Advanced materials play a crucial role in modern engineering applications where they are often exposed to complex loading and environmental conditions. In many cases, new approaches are needed to characterise these materials and to model their behaviour. Such approaches should be calibrated and validated by specific experimental techniques, quantifying both microstructural features and respective mechanisms at various length scales. The book provides an overview of modern modelling tools and experimental methods that can be employed to analyse and estimate properties and performance of advanced materials. A special feature of the book is the analysis of case studies used to demonstrate the strategies of solving the real-life problems, in which the microstructure of materials directly affects their response to loading and/or environmental conditions. The reader will benefit from a detailed analysis of various methods as well as their implementation for dealing with various advanced materials.

Non-linear Modeling and Analysis of Solids and Structures
This book presents a theoretical treatment of nonlinear behavior of solids and structures in such a way that it is suitable for numerical computation, typically using the Finite Element Method. Starting out from elementary concepts, the author
systematically uses the principle of virtual work, initially illustrated by truss structures, to give a self-contained and rigorous account of the basic methods. The author illustrates the combination of translations and rotations by finite deformation beam theories in absolute and co-rotation format, and describes the deformation of a three-dimensional continuum in material form. A concise introduction to finite elasticity is followed by an extension to elasto-plastic materials via internal variables and the maximum dissipation principle. Finally, the author presents numerical techniques for solution of the nonlinear global equations and summarizes recent results on momentum and energy conserving integration of time-dependent problems. Exercises, examples and algorithms are included throughout.

Structural Stability of Steel: Concepts and Applications for Structural Engineers
By Theodore V. Galambos, Andrea E. Surovek
Publisher: Wiley 2008-04-18 | 384 Pages | ISBN: 0470037784 | PDF | 10 MB
Practical guide to structural stability theory for the design of safe steel structures
Not only does this book provide readers with a solid foundation in structural stability theory, it also offers them a practical, working knowledge of how this theory translates into design specifications for safe steel structures. Structural Stability of Steel features detailed discussions of the elastic and inelastic stability of steel columns, beams, beam-columns, and frames alongside numerous worked examples. For each type of structural member or system, the authors set forth recommended design rules with clear explanations of how they were derived.
Following an introduction to the principles of stability theory, the book covers:
*
Stability of axially loaded planar elastic systems
*
Tangent-modulus, reduced-modulus, and maximum strength theories
*
Elastic and inelastic stability limits of planar beam-columns
*
Elastic and inelastic instability of planar frames
*
Out-of-plane, lateral-torsional buckling of beams, columns, and beam-columns
The final two chapters focus on the application of stability theory to the practical design of steel structures, with special emphasis on examples based on the 2005 Specification for Structural Steel Buildings of the American Institute of Steel Construction. Problem sets at the end of each chapter enable readers to put their newfound knowledge into practice by solving actual instability problems.
With its clear logical progression from theory to design implementation, this book is an ideal textbook for upper-level undergraduates and graduate students in structural engineering. Practicing engineers should also turn to this book for expert assistance in investigating and solving a myriad of stability problems.
