As is shown in our previous work, the energy release rates for viscoelastic bodies are equal to the rates of crack-closure energy. By using the solution for the e~~ck-border stress and displacement fields of viscoelastic solids, the time dependent G,-Ki relationships for viscoelastic cracked bodies
A new type of finite element is introduced which embodies the inverse square root singularity present near a crack in an elastic medium. Using this element near the tip in two typical cracked configurations, stress intensity factors within 5 per cent of accepted values were obtained with meshes havi
Stress intensity factors have been determined directly for certain special crack problems with the help of J or other path-independent integrals. Such procedures have not been used successfully in what are perhaps the most classical of all crack problems: those in two dimensions involving a crack of
