Material models in PAM-STAMP


Audience

CAE engineers, model designers, and experienced manufacturing engineers involved in the stamping process

Objectives

Understand the theory and the formulation of algorithmic problems in order to carry out formability assessment studies with the PAM-STAMP complete stamping solution.

Prerequisites

Course: PAM-STAMP: Full stamp value chain (STA-B) – Mandatory day + PAM-AUTOSTAMP (3 days), or equivalent experience
