Abstract
A shearing interferometric method (CGS) is used to study dynamic crack-tip fields in both transparent and opaque media. CGS is a full-field optical technique that provides real-time fringes representing crack-tip deformation or stress state. The results of the experiments are interpreted on the basis of a newly developed transient higher-order asymptotic analysis. The good agreement between the experimental results and the transient higher-order asymptotic analysis clearly indicates that the contribution of the non-singular terms to the total stress and deformation fields is significant.
