Bulge Test for Material Formability Evaluation
August 23, 2019Tensile testing over time is the first step in determining property variation for new-material forming. However, industrial stamping processes often experience higher strain that surpasses tensile-testing capabilities. For these instances, bulge testing can dramatically improve the accuracy of the yield surface of new materials.
The EWI Forming Center, Columbus, OH, recently developed bulge test capability to obtain flow stress of sheet metals to the highest strain level before necking. This differs from conventional bulge testing by adopting digital image-correlation cameras to determine bulging height and curvature profile for strain calculation.
