[Eric Kam]not that I recall. You had sent over notes before on a different, but similar system.
[Jim Peck]Eric Kam, Did we discuss Phast previously?
[http://www.worldautosteel.org/ulsac/328.htm] Circle grid strain analysis in the ULSAC program was performed to determine real strains or material thinning and material thickening of the three-dimensional stamped parts. Those measured strain and material thinning values were compared with the forming simulation results. Corus NL Research & Development performed the circle grid strain analysis on the stamped parts. They are equipped with the latest system for strain measurement, called Phast, which is jointly developed by Geodelta and Corus NL Research & Development. Phast is a vision-based measurement system that determines surface strains on formed sheet metal. The measurement errors are between ±0.5% (absolutely). The first step was to apply a point circle grid pattern on the flat steel sheet by electro-chemical etching prior to the stamping process.
