Physical and Phenomenological Model with Non-Linearity in Ductile Fracture and Fatigue Crack Growth

  • Conference paper

Summary

This paper concern the ductile fracture with respect to large scale non-linear plasticity, and concern the fatigue crack growth at not high temperatures with respect to small scale non-linear plasticity.

Concerning the ductile fracture, a physic-phenomenological model has been presented both for slipping-off type and for separation type, respectively. For separation type fracture, the piling-up of dislocations problems have been studied by computer simulation based on dislocation group dynamics.

Concerning the fatigue crack growth, a physicophenomenological model has been presented. The crack growth rate formula based on this model is in common with any of physical models, such as, nucleation model, dislocation group dynamics model or vacancy condensation model as far as stress intensity dependence is concerned.
