Influence of Continuum Damage on Stress Distribution Near a Tip of a Growing Crack Under Creep Condito account by Rabotnov-Leckie-Hayhurst constitutive equations. The stress and damage fields analysis is carried out for anti-plane shear, plane strain and plane stress conditions..A new type of stress and damage fields in process zone near a tip of a growing crack is obtained. It has been shown that

Dislocation Movement at Crack Tip of Single Crystals of Ice. Dislocation pile-ups were observed in front of the tip of an arrested cleavage crack in the prism plane. A dislocation-free-zone of length 750.m between the crack tip and the etching tracks was found for the first time in an ice crystal subjected to creep. These etching tracks corresponded to the

Creep Crack Growth Prior to Stress Redistributiond also a step change in temperature are studied. Theoretical estimates of C(t) and hence crack growth are obtained. Finite-element analysis of a centre-cracked plate subject to a step temperature change is described and the results compared with the theory. For isothermal creep, it is shown that the

Microscopic Models and Macroscopic Constitutive Laws for High Temperature Creep and Creep Fracture oess creep curves to be extrapolated to predict long-term creep properties with impressive accuracy. The practical aspects of this approach to creep data prediction are discussed for creep brittle and creep ductile materials, with special attention focused on microstructurally-unstable alloys. The fa

Long-Term Creep Ductility Minima in 12%CrMoV Steelted by reference to previously published long-term creep data together with some new metallographic information. The observed minima are similar to those exhibited by most otner creep-resistant ferritic steels. The ductility behaviour has been modelled in terms of creep cavitation theory. The theory

Failure Criteria on Creep Rupture of Mineral Salt Based on Micromechanical Mechanismsglide band, but furthermore making use of the concept of activation energy. Basing on these theoretical considerations on crack initiation as well as on experimental evidence the growth of cracks under compression can be assigned to a one-sided deformation of the crack, that means entering of edge d

Volume Change and Energy Dissipation in Rock Salt During Triaxial Failure Testsnder various conditions..Therefore, equipment for precise true triaxial tests on cubic specimens and a special test procedure for quasistatic failure tests on rock salt have been developed. Deformation, volume change, and irreversible stress work were calculated from the empirical data as a function
