Abstract

The direction of crack noncolinear propagation of composite material is observed by geometric moire' method. GFRP specimens with single edge notched are subjected to static and dynamic tension. Moire' patterns representing displacement component perpendicular to the reference gratings are taken. From these patterns, curves of strain distributions with polar coordinate are obtained. Directions of crack propagation obtained by moire' method are agree with practice.
