In this paper, the mechanical behavior and damage evolution of CFRP laminates under three-point bending loads were investigated. Based on three-dimensional Hashin failure criterion cohesive zone method, a progressive analysis model was constructed to predict seven different modes, an improved stiffness matrix degradation law proposed. Numerical simulations performed using ABAQUS finite element ...

The T ∗ ε integral was calculated numerically along an extending, tunneling crack front in an 8 mm thick, aluminum three-point bend (3PB) specimen, using a numerical model driven by experimentally obtained surface displacements. The model provided input to a contour integration for the T ∗ ε integral, via the Equivalent Domain Integral (EDI) method with incremental plasticity. Validity of the a...
