We had the honor to be selected as the computer simulation partner for a recent Auto/Steel Partnership (A/SP) study that considered the feasibility of using higher strength and advanced high-strength steels to achieve weight reductions of hemmed closure panels: project…

For the continued growth of tube-hydroforming, better methods for creating and validating springback compensation are essential. Upcoming vehicle programs forecast increasing use of Advanced High-Strength Steel along with more tube-hydroformed parts.  The release of AutoForm-HydroDesigner2016 represents the first commercial solution…

As already discussed in Sheet metal plasticity visualized (part one) there are four main components needed to model the plastic deformation of sheet metals: yield function, hardening model, flow rule, and failure model. We have expanded our discussion of the…

Springback of sheet metal stamped parts is a challenge faced by tooling suppliers and their customers; parts produced in stamping dies require significant effort in engineering and simulation to arrive at reasonable dimensional accuracy during process design. Conventional methods for…

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…

Springback in sheet metal stamped parts is an often discussed topic. However, springback of closed-section tube-hydroformed parts is addressed less often. One possible reason for the delayed focus closed-section parts may be that tube-hydroformed parts achieve desirable strength-to-weight performance when…

Earlier this year AutoForm started this blog, “We Think In Sheet Metal”. Our goal: to communicate directly with you—the metal forming and engineering community.  Here are some of our recent blog posts; please share them with your colleagues, customers, and…

Have you ever defined a hot forming process virtually? How do you determine which design and process parameters are required for the production of a high quality hot formed part? Finite Element Analysis (FEA) is an appropriate tool to engineer…
