โœฆ Synopsis

The process of subcritical crack growth in a center-cracked specimen made of 20!4-T3 aluminum alloy has been analyzed by finite element method. The variations of various fracture parameters in the process of crack growth are presented. A preliminary discussion is made about the general guidances in formulating the governing equation for crack growth.

A nonlinear finite element analysis, based on the incremental theory of plasticity with isotropic hardening rule, has been performed for the process of slow crack growth in center-cracked specimens made of 2024-T3 aluminum alloy. With experimental data relating the applied stress and the crack size
