Abstract: The results of the measurements of spall strength of polycarbonate at a maximum compression stress of 0.6 GPa in the initial temperature range of 20–185$^\circ$C are presented. It has been found a significant decrease in the spall strength when the polycarbonate reached the glass transition temperature. The strain rates in the plastic compression wave are determined depending on the maximum stress under single and stepwise shock compression. The dependences of the shock wave velocity $U_S$ – mass velocity $u_p$ in the range of maximum shock compression stresses up to 0.8 GPa at different temperatures are constructed.
Keywords: polycarbonate, shock waves, deformation, temperature, spall strength, shock adiabate.
