Abstract
The use of a coherent gradient sensing (CGS) apparatus is explored in dynamic fracture mechanics investigations. The ability of the method to accurately quantify mixed-mode crack tip deformation fields is tested under dynamic loading conditions. The specimen geometry and loading follow that of Lee and Freund1, 2 who give the theoretical and numerical mixed mode K values as a function of time for the testing conditions. The CGS system's measurements of KI and KII are compared with the predicted results, and good agreement is found.
