A Finite Element Model of Local Damage in Creep Rupture

This paper presents a finite element model of local damage in creep and provides the threshold strain for damage elements. The essence of localized damage theory is that materials could be divided into several different groups with different creep damage and proved by stress redistribution. Calculation has been made on a double V notched bar. The crack initiation time and rupture creep strain are coincided with the experimental results.
