Investigating the effects of crack geometry and location on crack growth behavior in a centrally perforated cylinder under internal pressure

摘要：

In this study,the frozen stress photoelastic method was used to investigate the three-dimensional effect on the crack growth behavior in a centrally perforated cylindrical cylinder under internal pressure.The inner surface of the cylinder had a star shape,which consisted of six fins.The experimental data were analyzed.The three-dimensional effect and the crack location on the crack growth behavior and the role of shear modes during crack turning were investigated and the results are discussed.
