While, experimental method performs to be effective due to its independence on materials. Because of deficiency on the present experimental techniques, there is less experimental analysis of large deformation fracture mechanics in recent reports.
而不受材料性能限制的实验测试方法,成为大变形断裂力学问题研究的有效手段,但由于受到实验技术的限制,目前工作甚少。
