Abstract/Additional Information

This report summarizes the basic results comparing program performance and stability between DYNA3D and LS-DYNA as well as the validation and benchmark testing of LS-DYNA. The finite element models (FEM) for Parker Dam and Black Canyon Diversion Dam were selected to be used as the test cases in comparing DYNA3D and LS-DYNA due to their size and contact surface complexity. The load application in this model is as follows: (1) Gravity and forces are applied from 0 to 3 seconds. (2) The model stabilizes from 3 to 6 seconds. (3) The ground motion begins at 6 seconds and runs until 20 seconds. Both DYNA3D and LS-DYNA are highly complex programs that produce valuable results for structural analysis issues. Several problem areas have been examined and compared using both codes.
