A two-dimensional plus spin computer program, EPIC-2, is described for impact and explosive detonation problems. The numerical technique is based on a Lagrangian finite element formulation in which the equations of motion are integrated directly rather than through the traditional stiffness matrix approach. Triangular elements are formulated for large strains and displacements, and nonlinear material strength and compressibility effects are included to account for elastic-plastic flow and wave propagation. Instructions for using the program are also included. Author
