Abstract:
A novel finite element scheme has been developed for simulating stress waves using 1-D, 2-D, and 3-D orthogonal curvilinear coordinate systems. Finite deformations and nonlinear material behavior are accommodated using a Lagrangian formulation. In addition, the explicit time stepping scheme is efficient computing rates of 0.4 and 1.2 m-sec per element per numerical time step have been achieved in 2-D and 3-D test calculations on the ILLIAC IV. About 50 percent slower computing rates were obtained in test calculations performed in 2-D and 3-D spherical coordinate systems.
