A Roadmap to Linear and Nonlinear Implicit Analysis in LS-DYNA
Below is a condensed presentation of our paper "A Roadmap to Linear and Nonlinear Implicit Analysis in LS-DYNA" that we presented at the 11th International LS-DYNA User's Conference in Salzburg, Austria on May 9-11, 2017.
Here's the Abstract: The default LS-DYNA settings are tailored for running large explicit analyses. For new and even experienced users, it can be challenging setting up an implicit LS-DYNA analysis to match analytical solutions or other standard implicit FEA codes. For example, the default element formulations are based on single-point integration whereas implicit analyses benefits from full-integration. A series of example problems are provided that will allow the simulation engineer to exactly match industry standard implicit codes (complete keyword decks can be found at DYNAsupport.com). Along with these example decks, CPU-scaling results will be presented for each implicit analysis type from linear to nonlinear.
