Improved Implicit Structural Simulations
2013 (English)Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

This master thesis deals with the application of implicit methods in tow hook simulations. The event studied is quasi-static and results are compared between LS-Dyna explicit/implicit and data from physical tow hook component testing. The main goal is to get faster and more accurate results from the implicit simulations that currently can be applicable in the development work of Gestamp Hardtech. Stability of the different methods used is tested and accuracy of the implicit solver of LS-Dyna examined. The results show that the speed of the implicit solver is greater than its explicit counterpart but more accurate component tests are needed to validate the implicit method.
