I will read you paper tomorrow and see if I can pick up some questions. Thanks for providing the movie!</p> <br class="clear" /> Sun, 04 Mar 2007 23:45:26 -0500 Henry Tan comment 1458 at http://imechanica.org http://imechanica.org/node/976 <p>This high-speed photography image shows a mode I crack (representing by a symmetric photo elasticity fringe pattern) is approaching a weak interface in a brittle polymer (Homatel-100). The crack tip speed is around 300-400 m/s. There will be three possibly situations for dynamic interfacial failure mode transitions : 1) crack kinks at the interface, 2) crack directly penetrates the interface and 3) interface debonding occurs before the incident crack reaches the interface. Which case will occur?

It will take a few minutes to access my movie site since the size of each movie is quite large. But the movie resolution and layout from my site is much better than the movie from YouTube (below). &copy; Dr. L. R. Xu (Vanderbilt University) and Dr. A. J.
