Opis

Procedures for designing against fatigue in many products and structures make reference to crack propagation, however the stochastic behavior of this phenomena is not widely covered in publications. Introducing the stochastic behavior of crack growth to the analysis and design procedure allows engineers to optimize for reliability. Each chapter of Stochastic Crack Propagation describes a feature important to the analysis of stochastic crack propagation, starting with the essential background theory. Processes or phenomena which are of practical importance in the work of design engineers or R&D teams are described chapter by chapter. Many examples are described and supported by listed references, and files of data that can be used with specialist software to practice design situations. Advice on how to use various computer programs to design and predict for stochastic crack growth is provided, providing a complete guide for professionals.

• Presents instructions and exercises in the ideal format for professionals, focusing on applications
• Explains a methodology for how to optimize the engineering design process by including stochastic crack growth behavior
• Provides computational files to help readers get up to speed with designing using programs like ANSYS and NASTRAN for stochastic crack growth

O autorze

Giora Maymon obtained his doctor of sciences from Technion Israel Institute of Technology, 1975. He has worked in RAFAEL-Armament Development Authority since 1963, so he has more than 50 years of experience in practical project oriented design. The work was centered on structural analysis and testing, structural dynamics, probabilistic structural analysis and stochastic crack propagation. He is author of two books (one published by the AIAA and one by Elsevier), and a participant in another two edited books. Details on publications and conference presentations are given in http://gioram.webs.com. He has more than 20 years of experience in stochastic crack propagation, and wrote numerous RAFAEL internal reports on the subject.
