... Dynamic This enhancement to LS-DYNA Commercial Composite enables the most effective and code Simulator accurate dynamic progressive failure module of modeling of composite structures LS-DYNA currently available. The integration of this module, known as MAT 161, into LS-DYNA allows users to account for progressive damage of various fiber, matrix, and interplay delamination failure modes.

... dependent, nonlinear deformation and failure responses of composite materials in which the matrices are ductile polymers. Modified versions of the Ramaswamy-Stouffer constitutive equations of viscoplasticity, originally developed for metals, are used to represent deformation of a polymeric matrix.
