Description Stable crack growth in mixed mode through three point bend (TPB) specimens of D16AT aluminium alloy has been studied both theoretically and experimentally. Theoretical investigations are based on an elastic-plastic finite element scheme based on the small deformation theory of incremental plasticity. The crack edge profiles and the plastic wakes have been obtained by the replication method and the chemical etching technique respectively. The finite element results include load-displacement diagrams, plastic zones, crack edge profiles, J integrals, etc. Comparison with experimental results has been presented in some cases. The agreement is generally good. The crack growth at every stage appears to be governed by the crack opening angle (COA) criterion.
