Hot Forming with LS-DYNA

In this course, participants are taught the basics of thermal and thermo-mechanically coupled simulations using LS-DYNA. In addition, the definition and basic forms of heat transfer will be reviewed. Due to its increasing relevance, special attention will be drawn on the application of thermal and coupled simulations of hot and cold forming processes. Among other things, the available material models will be described covering plasticity, viscoplasticity, anisotropy, and structural transformation of steel. Besides the modeling methods of the main physical effects, a focus is placed on illustrating an efficient modeling techniques that are adapted to the calculation task at hand.
