Abstract

A custom biaxial testing fixture was used to evaluate new cruciform geometries. Specimens consisting of AA5083, Mg AZ31B, and TWIP steel were quasi-statically deformed to failure at 300oC. We elucidate geometric differences between specimens that accumulate plastic deformation within their gauge areas and those that prematurely fracture. Strain fields are computed with digital image correlation for selected geometries.
