摘要 本文采用线弹簧单元与ＡＤＩＮＡ程序结合计算了表面裂纹在交变载荷作用下的应力强度因子，首次提出了预埋线弹簧单元法模拟表面裂纹疲劳扩展，并发展了相应的技术和软件。 The stress intensity factor of surface crack under cyclic loading is calculated by using the Line-Spring Moding and ADINA. The method of presenting Line-Spring Elements is proposed for the first time to simulate the fatigue growth of surface crack, and corresponding technique and software are developed.
