The Elastic-plastic finite element alternating method (EPFEAM) and the prediction of fracture under WFD conditionsin aircraft structures

摘要

This report provides a summary of the Elastic- plastic Finite Element Alternating Method (EPFEAM), the T*-integral fracture mechanicds parameters, and the use of Both tools to predict the residual strength of aircraft panels With multiple-site damage. Because this report is meant to Be self-contained and each of the three subjects of a con- Siderable research topic in itself, the report is written in Three parts. Part I, EPFEAM Theory provides a summary Of the elastic-plastic finite element alternating method (EPFEAM) and the lagorithms for fracture analysis and crack growth predictions.
