ABSTRACT
In order to investigate the behavior of cracks, Wu [19] considered unidirectional fiberglass-reinforced Scotch-plies with center cracks oriented in the direction of the fibers. The plies had fibers in the 0◦ and 45◦ directions and were loaded in tension, pure shear, and combined tension and shear. In all three types of loading, it was observed that the crack propagated in a direction co-linear with the initial crack.
