Contact Modeling in LS-DYNA

In many simulated systems, the contact behavior between different components are an essential part of the process to be modelled. Driven by the increased demands for a wider range of applications of computer simulations, new numerical methods or multi-physical applications, the existing possibilities for contact description in LS-DYNA are constantly being developed further or have been supplemented by new methods.

As a result, over the years LS-DYNA has gained a vast amount of contact-treatments possibilities inside the simulation model.

However, due to this variety, it becomes more and more difficult for the user to choose the suitable contact algorithm together with the suitable parameters.

In this seminar the theoretical background of the different contact formulations of LS-DYNA together with their application possibilities and limitations will be addressed in detail. This will enable the user to select the appropriate contact type for its application together with the appropriate control parameters. The course is supported by numerous practical examples, which are intended to deepen the previously conveyed basics in a practical way.
