A Viscoplastic Constitutive Relationship and the Finite Element Implementation of Stress/Strain Concentration in Notched Component
This paper deals with a unified inelastic constitutive model and its application to finite element implementation. In the first part, the validity of the constitutive model is evaluated under complex loading history. The finite element formulation is then obtained, based on the constitutive model proposed. The local strain response is analyzed for notched cylinder, being compared with the axial/torsional strain response near the notched root.
