Abstract

High-speed recording techniques in conjunction with methods of photomechanics serve as a means for visualizing the highly complex interaction processes between elastic stress waves and geometrical discontinuities such as boundaries, interfaces, cracks and contact surfaces. Four topics of importance and general interest will be addressed here: the interaction between elastic stress waves and static or running cracks, mixed-mode crack propagation, dynamic contact of impacting bodies and stress wave focussing effects. Experimentally recorded isochromatic fringe patterns and sequences of caustics assist and confirm numerical and analytical computations.
