Description Stable crack growth in mixed mode through doubly stiffened and unstiffened compact tension (CT) specimens of D16AT aluminium alloy has been studied theoretically and experimentally. Theoretical study is based on an elastic-plastic finite element scheme based on the small deformation theory of incremental plasticity. The plastic wakes have been obtained by the chemical etching method. The finite element results include load-displacement diagrams, plastic zones, crack edge profiles, J integrals, etc. Comparisons with experimental results have been presented in some cases. The agreement is generally good. The crack growth at every stage appears to be governed by the COA criterion.
