Download or read book Computer-Based Prediction of Cyclic Deformation and Fatigue Behavior written by Conle A and published by . This book was released on 1988 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: The paper briefly reviews the history of rheological spring-slider based, stress-strain models, and the early computerized versions used to simulate cyclic deformation and predict fatigue life. A set of rules is introduced which allows cycle by cycle simulation of the local stress-strain behavior at the root of a notched component subjected to any variable amplitude load history; predicts the crack initiation life; and, with two modifications to the notch analysis and the fatigue damage summation routines, models the local stress-strain behavior at the crack tip and resulting crack propagation rates. Supporting software that has resulted in practical applications for automotive design is discussed.
