Formability Evaluation

Abstract: This project investigates the possibility of using material thickness measurements of pressed stainless steel (316L) and titanium (grade 1) sheet metal to evaluate material formabil- ity. The ultimate goal of this project is to replace the current subjective visual material formability evaluation with an objective method. This project attempts to build relation- ships between material surface defects that are visually identified and the material thickness which is measured using 3D laser scanning. Formability evaluation methods are compared to asses the strength of these relationships and the feasibility of replacing the current evaluation method.
