Description
WIT Press How Gears Break v. 18 2004 Edition by B. Abersek, J. Flasker
This book presents an in-depth study of the failure mechanisms of gears and describes how simulation models can be developed to complement or replace experimental tests. The authors first introduce the physical processes of failure and explain how to analyse these using fracture mechanics. Much of the following text is devoted to mathematical models and formulations that can be used to predict how cracks behave in gears, together with special techniques developed by the authors. The concluding section describes an expert system devised by them for the design of gear assemblies. References are included at the end of each chapter. "How Gears Break" will be of interest to engineers specialising in damage and fracture mechanics as well as designers of gear assemblies.
