N2 - The results of experimental investigation of crack propagation in PMMA plate samples under quasi-static and dynamic loading are presented. The quasi-static loading was carried out using a tensile-testing machine. The dynamic loading was carried out by means of the installation of conductor explosion. The results of both dynamic and quasi-static experiments show the unstable behavior of the instantaneous crack velocity. However the mean speed of the crack tip propagation depends on the type of the load.
