| Abstract: | Crack propagation in polymethylmethacrylate shock-stressed by a pulsed magnetic field is experimentally investigated. The failure type as a function of the distance from the crack tip is analyzed, and the failure diagram is constructed. The surface failure energy is estimated. The tilt angles of mesocracks are correlated to the failure type. |
