Crack Tip Stress

The elastic problem of a crack normal to a bimaterial interface is addressed in the context of unidirectional fiber composites. The structure of asymptotic crack-tip stress fields is obtained numerically. The numerical results are then analyzed to formulate criteria for assessing cracking normal to the fiber, interface splitting, and fiber pull-out.

Wedge Splitting

Two parameter fracture mechanics uses for description of the crack tip stress fields, not only the stress intensity factor (SIF), but the second term of Williams expansion the T-stress. In the paper, the SIF and T-stress of typical wedge splitting specimens with usual loading arrangements varying in the wedge angle are directly computed using ANSYS finite element software. The influence of the wedge angle value is quantified.
