In Finite Element Analysis, it is common to treat the metal restraint due to draw beads as numerical factors applied along a curve or set of curves. The use of these factors makes defining boundary conditions simple and computationally effective….

In our previous post on the stamping system, several environmental variables within production sheet metal stamping are mentioned. In that post we listed variables such as blank surface, blank coating, tool surface, tool coating, and blank/die lubrication. These variables are…

The Stamping System

A recurring theme on this blog, so far, has been sources of variation in production that might not be apparent to engineers when defining, running, and evaluating a single simulation on any specific product/process design. Comments on the blog and…

Do you ever think about the numerous options for draw bead modelling? When and why should we use numerical line beads? When is it best to use mesh bead geometry? Is there a way to benefit from both? To achieve…

Sometimes a stamping process engineered and validated using simulation will differ from the results of the die once it is built. One might wrongly conclude that “the simulation was wrong,” or “bad steel,” or blame the toolmakers. Instead, consider that…
