摘要：

Backman and Finnegan [1] have pointed out that shear bands initiate from a defect such as a second phase particle, microcrack, or a void. The defect has been modeled as a sinusoidal variation in the thickness of the tubular specimens tested in torsion by Chi [2] and Murphy [3]. Here we simulate their torsional tests numerically and consider different shapes and sizes of defects.
