Phast system for CGA
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.

Ultralight Steel
The Ultralight Steel Auto Closure (ULSAC) Program is a study undertaken by the global steel producers to demonstrate the effective use of steel in producing lightweight, structurally sound steel automotive closures that are manufacturable and affordable. ULSAC began as a concept development program, producing lightweight designs for doors, hoods, decklids and hatches that are up to 32% lighter than the average benchmark.
