The damage theory is used to study the region of the crack tip and the crack tip damage field is obtained. A near-field damage criterion D|r=dr =Dc is proposed based on micro experimental analysis and the relationship δc-dT between macro mechanical parameter and the microstructural parameter of material is established. The microstructural change around the crack tip during experimental loading as well as crack propagation has been observed with SEM. The damage criterion...

The damage theory is used to study the region of the crack tip and the crack tip damage field is obtained. A near-field damage criterion D|r=dr =Dc is proposed based on micro experimental analysis and the relationship δc-dT between macro mechanical parameter and the microstructural parameter of material is established. The microstructural change around the crack tip during experimental loading as well as crack propagation has been observed with SEM. The damage criterion relationship is verified by experimental results and it is shown that the stress, strain and damage at a certain distance from the crack tip are important factors for the control of tough fracture.
