In this paper, the crack propagation in the compact-tension-shear (CT)specimens of elastic-plastic materials, 7005 aluminum alloy under mixed-mode loadingconditions is studied numerically and experimentally. The elastic numerical methodwhich uses the maximum circumferential stress σθθmax and elastic-plastic method, J-Mpbased criterion developed by the authors recently [4], are used in order to estimate thegrowth direction of a crack in elastic-plastic materials under cyclic loading andmonotonic loading. A series of static and fatigue experiments are carried out. A mixed-mode-loading device developed by Richard [8] and the CT specimens are used in theseexperiments. The photos of crack growth paths subjected to different mixed-modeloading conditions are presented in this work. The experimental results show that theplastic zone has important effect on the direction of crack growth path, especially in thecase of monotonic loading. Furthermore, the use of J-Mp based criterion is discussed bycomparing the numerical simulations and the experimental observations.
