HF-1010: Increasing Blankholder Pressures

In this chapter, you will learn how to increase blankholder pressure and compare the results from different pressure levels. The result from the previous tutorial, One-Step Stamping Simulation (HF-1000), will be used to compare the result from this tutorial.

Exercise: Increasing Blankholder Pressures

This exercise uses the model file Blank_holder.hf.
