STRAIN-DEPENDENT CREEP DAMAGE IN RANDOM IN HOMOGENEOUS MATERIALS

Employing a recent homogeneous strain-dependent creep damage theory, the propagation of a failure front in a beam under pure bending is studied. A local inhomogeneous strain-dependent creep damage theory is postulated, based on creep damage data obtained at J.R.C. Ispra. Solutions for various loading conditions are obtained, and are shown to be in better agreement with observation than previous theories. The effect of random material parameters on the rupture time is considered for the constant tensile stress test and for the beam under pure bending.
