Implicit door-hinge analysis depicting the resulting von Mises stress This commonly executed mis-use load case in automotive industry. A computer simulation is challenging in various ways. For instance, on the one hand, a robust contact algorithim is necessary and, on the other hand, the solution procedure needs to be acurate and stable over longer simulated time periods. To cope with this, LS-DYNA comes with the Mortar contact algorithm providing accuracy and robustness when running implicit simulations. Moreover, LS-DYNA allows for an easy swtich from explicit crash simulation to implicit analysis, thus, saving a significant amount of conversion time.
