Method of constructing shock compression diagrams for foam plastics

A method is proposed for constructing shock compression diagrams for foam plastics based on experimental determination of the residual deformation of a specimen after impact with a rigid obstacle. An approximate diagram is obtained for expanded polystyrene PS-1 of initial density 0.21 g/cm³, and the dynamic yield strength is estimated.Moscow.
