Abstract
Experimental work has reported dependency of forming limits on sheet thickness. The present paper reveals possible explanations based on finite element simulations incorporating an internal length scale. Using an incorporated length scale, it is possible to take into account thickness effects in a membrane analysis and the microstructure in a full 3-D analysis. Both the point for inset of localization (forming limits) and the post-necking behaviour were found to depend on the incorporated length scales.
