The effect of defect size on the stress concentration and fracture characteristics for a tubular torsional model with a transverse hole.


The maximum stress location and crack resistance of a tubular torsional model with varying transverse circular defects were determined by the use of experimental and global-local finite element modeling techniques. The experimental results showed that the reduction in torsional strength was inversely proportional to defect size. In addition, the maximum… (More)
