Abstract

A crack is considered as a very thin failure zone but not an ideal discontinuous surface. Using a new constitutive relation that contains all of the three stages of creep, the deformation field near a Mode I growing crack tip is analyzed. The stress and strain remain finite at the crack tip. Asymptotic equations of the crack tip field are derived and solved numerically. Besides the local autonomy of crack tip field is discussed.
