heal.abstract	The optical method of caustics was used along with high speed photography to study crack propagation and crack-hole interaction in plane PMMA specimens containing a transverse edge crack and a hole lying eccentrically to its axis. The specimens were fractured under different dynamic loads. Crack-hole interaction is characterized (for a limiting vertical distance of the crack axis from the center of the hole) by a process of attraction - repulsion of the crack towards the hole, interrupted by a momentary crack-arrest at the hole boundary. Increased values of crack propagation velocity and of the stress intensity factor at the tip of the propagating crack are detected during crack-hole interaction. © 1988 Springer-Verlag.	en
