WARP3D

WARP3D is under continuing development as a research code for the solution of very large-scale, 3-D solid models subjected to static and dynamic loads. Specific features in the code oriented toward the investigation of fracture in metals include a robust finite strain formulation, a general J-integral computation facility (with inertia, thermal, face loading), interaction integrals for computation of linear-elastic fracture parameters, very general element extinction and node release facilities to model crack growth, nonlinear material models including viscoplastic and cyclic, cohesive elements and cohesive constitutive models, and the Gurson-Tvergaard dilatant plasticity model for void growth. The source code is distributed free of charge under the GNU license.
