The present paper is aimed at finding a method of predicting the direction of the fatigue crack propagation and fatigue life under general in-plane load. The main points are:(1) we presented a new fracture criterion that the fatigue crack extension takes place in the direction in which σθ is maximum in the equal twin shear stress Line. The extension directions of cracks predicted by this criterion are more approximate to those obtained by exeperiments than by any other fracture criterions.(2)...

The present paper is aimed at finding a method of predicting the direction of the fatigue crack propagation and fatigue life under general in-plane load. The main points are:(1) we presented a new fracture criterion that the fatigue crack extension takes place in the direction in which σθ is maximum in the equal twin shear stress Line. The extension directions of cracks predicted by this criterion are more approximate to those obtained by exeperiments than by any other fracture criterions.(2) We have pointed out that it is the direction of the branch of Z-shaped cracks that plays an essential role in the values of K_Ⅰ, K_Ⅱ.(3) In order to predict fatigue life of mixed mode fatigue crack propagation, a new formula for fatigue growth rate, an exponential formula of the converted extensional stress intensity, factor, is derived The fatigue life predicted by this formula are more approximate to those obtained by experiments than by any others.Besides, we discussed about the application of the principal stress intensity factor——K~*, strain energy release rate——G, strain energy density factor——S, to predicting the fatigue life.

本文要解决的是平面复合型疲劳裂纹扩展方向以及疲劳寿命的预测问题。主要内容如下: 1.提出“等双剪应力线上δθmax平面复合型裂纹开裂判据”。与其它判据相比较;本判据所预测的裂纹开裂方向更接近于疲劳裂纹扩展试验的结果。 2.文中指出:是Z形裂纹的分支方向,而不是其主裂纹方向,在Z形裂纹的K_Ⅰ,K_Ⅱ值中起着支配性的作用。接着提出二个计算Z形裂纹应力强度因子的近似方法。 3.为预测复合型疲劳裂纹扩展的寿命,文中提出了一个新的裂纹扩展速率表达式,即折合张应力强度因子指数公式。此式所预测的寿命较接近于实验值。 最后,还讨论了应用主应力强度因子K~*,应变能释放率G,应变能密度因子S,预测复合型疲劳裂纹扩展的寿命问题。

Following a previous paper by the same author, the fracture process of the Tangshan Earthquake of July 28, 1976 is hereby further studied. A three dimensional mechanical model is now presented and more complete results in comparison with that by two dimensional model are obtained. It is found that there exists an alpha (α) angulad region of about 10?near each end of the major axis of the main fault. Within the angular region, the initial extension direction of points on the fault front is no longer coplanar with the plane of the main fault but in a plane making an angle (φ0,θ0) with it. However for other parts of the fault, the front extents in the fault plane. Near the end points of the major axis the angle φ0≈0 θ0≈80.5 °They agree with the didections obtained from two dimensional analysis. It is because that the extension within the angular region of about 10?at the end points of the major axis of the fault plane is not coplanar, a large number of aftershocks occurred along this direction. So the fault plane becomes contorted in shape.

本文提出一个三维力学模型,对1976年7月28日唐山地震的破裂过程做了进一步的理论分析。结果表明断裂面长轴两端存在一个10°左右的α角域,在这个角域内断裂面前缘的初始扩展方向是非共面扩展,即在与断裂面本身偏离一个角度(φ_0,θ_0)的面内扩展,而在其它区域断裂面的前缘是沿自身平面扩展的。在邻近长轴端部的点,扩展角φ_(?),0o=80.5°,这和二维分析得到的扩展分支的方向一致。由于主断裂面在长轴端部10°角域左右的非共面扩展,大量余震沿此方向发生,断裂面变成扭曲形状。
