What is it about?
In this work the results of experiments on notched and cracked polymethyl methacrylate (PMMA) beams which have been subjected to tensile and impact loading have been reported.The fracture surface energy by the method of caustics using the second step of the propagating crack has beeb measured by the method of caustics

Why is it important?
Because the fracture surface energy is an important property of the material.
