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.
