Effect of microstructure degradation on creep crack growthostructure degradation is incorporated in the material model that describes the nucleation and growth of cavities in the grain boundary, including the effect of diffusion, dislocation creep and grain boundary sliding. It is found that the creep acceleration significantly reduces the notch sensitivit

Influence of damage on crack-tip fields under small-scale-creep conditionsg of the transient crack-tip fields under small-scale-creep conditions is limited primarily to analyses based upon creep flow rules that neglect damage. In this paper, Kachanov-type creep-damage constitutive equations are developed that include the dilatational creep that arises from caviation and m

On some path independent integrals and their use in fracture of nonlinear viscoelastic mediamedia. In this paper we discuss some situations in which such quantities exist and are useful in the study of quasi-static initiation and continuation of crack growth. The so-called quasi-elastic approximation and a constitutive equation in the form of a single hereditary integral provide the basis

Dynamic measurement of the , integral in ductile metals: Comparison of experimental and numerical te described. A relation between the caustic diameter, ., and the value of the . integral was obtained experimentally and numerically for a particular statically loaded specimen geometry (three point bend) and material (4340 steel). Specimens of the same geometry and material were then loaded dynamica
