LS-DYNA Kompakt: Introduction to Welding Simulation

Recent developments in LS-DYNA target to close the virtual process chain with respect to the thermal-mechanical coupled process steps such as line welding and resistance spot weld. In this webinar most of these developments are discussed. New boundary conditions and contact algorithms for the thermal and the structure solver of LS-DYNA are introduced that provide a flexible and comfortable framework to set up welding simulations. Furthermore, the webinars covers coupling approaches for the transfer of temperature fields to a structure simulation and also tailored material models for the process.

The course will take place from 9-11 a.m. on two consecutive days.

Please note: The course will be held in Ansys Learning Hub. We will send the credentials shortly before the training.
