... ). In linear elastic or K -based fracture, the crack tip should remain sharp during crack advance, with little to no blunting caused by yielding or viscoelastic mechanisms in front of the crack tip ( Ref 5 , 13 ). In elastic-plastic or J -based fracture, the crack tip generally blunts due to yielding...
