Crack Propagation in Transparent Materials under Different Types of Loading
|
Crack propagation under quasi-static tensile of PMMA plates with notch (X axis - time, Y axis - crack length) |
Crack propagation in PMMA plates with a notch under localized pulsed action on the notch faces (X axis - time, Y axis - crack length) |
We consider various problems of crack propagation in specimens of organic glass under quasi-static and dynamic loads. The method of crack registration allows to obtain the quasi-continuous time sweep of the crack trajectory in the range of 200 ns - 0.5 ms.
