摘要
应用能量原理和断裂力学理论对原有的线弹簧模型进行了扩充，导出了线弹簧模型在两种以上荷载作用下，柔度与应力强度因子的关系式；分析讨论了钝裂纹尖端曲率半径和塑性区域对柔度变化的影响．
In this paper the extension of the original Line-Spring model is presented based on energy principles and fracture mechanics theories. From more than two kinds of loading is derived the relationship between compliance and stress intensity of the Line-Spring model. Besides the effects of curvature radias orplastic zone at the blunt crack tip on compliance changes are discussed.
