... they relate to fracture toughness and design process. The article explores the use of plane strain fracture toughness, crack-tip opening displacement, and the J-integral as criteria for the design and safe operation of structures and mechanical components. It discusses the variables affecting fracture...

In practice, the Tresca and von Mises criteria are most often used today to predict yield in isotropic constant-volume materials. The Rankine model is not often used because of its inability to predict behavior when one principal stress...
