Solution of dynamic contact problems by implicit/explicit methods. Final report
- California Univ., Berkeley, CA (United States). Dept. of Civil and Environmental Engineering
The solution of dynamic contact problems within an explicit finite element program such as the LLNL DYNA programs is addressed in the report. The approach is to represent the solution for the deformation of bodies using the explicit algorithm but to solve the contact part of the problem using an implicit approach. Thus, the contact conditions at the next solution state are considered when computing the acceleration state for each explicit time step.
