Effect of crack-tip plasticity on crack length estimation methods for SENB sample

This note is a discussion of “Crack length calculation for bend specimens under static and dynamic loading” by Jiang FC, Rohatgi A, Vecchio KS, Adharapurapu RR [Engineering Fracture Mechanics 2004;71:1971-85]. Crack-tip plasticity of SENB samples were evaluated and its effect on unloading compliance and crack length estimation were assessed by the FEA method.
