✦ Synopsis

Based on two microscopic failure models, the maximum tension stress criterion and damage criterion, the relationships of the scaling parameters of elastic-plastic stress fields for HRR field and different specimens were established in this paper. The two-fold applications of the relationships were explored by the experimental data and the numerical analyses for different thick compact tension (CT) specimens. It was found that the relationship on the basis of damage criterion is more appropriate than that on the maximum tension stress criterion for fracture assessments of different specimens.
