By theory of elastic contact the compression-shear mode is analysised. Cracks will be closed under compressionshear load. The magnitude of closed zone varies with the load applied. Considering the friction bettween the closed surfaces,the solution depends upon the loading path. They are problems of gemetrical nonlinearity of small elastic deformation.

By theory of elastic contact the compression-shear mode is analysised. Cracks will be closed under compressionshear load. The magnitude of closed zone varies with the load applied. Considering the friction bettween the closed surfaces,the solution depends upon the loading path. They are problems of gemetrical nonlinearity of small elastic deformation. By substructure finite element method, iterative process can be concentrated in the local zone of cracks. Thus, the tedious total stiffness matrix can be avoided so the time and space for computing are saved greatly.

压剪断裂属于弹性小变形几何非线性问题.本文应用于结构有限元法,把大量的迭代过程集中到包围裂纹的局部区域内,避免了对总体刚度矩阵的多次形成和求解,从而节省了机时和容量.

The initiation Speculiarity of the solid explosive charges under combined compression-shear loading is investigated in this paper. Two kinds of experiment about compression-shear loading have been carried out, one is the experiment in which compressionshear loading is realised by using the normal impacting quartz, and the possibility of chemical reaction taking place in the charges is analysed according to the movement of different partictcs inside the charge specimens measured dy means of electric-magneti particle velocity method; the other is the experiment in which the loading is realised by means of parallel inslant impact method on the compression-shear gun, and the possibility of charge explosion is observed. The experiments show that when the compression stress is under condition of sub-detonotion,the shear stress combining in the loading will play, a role in sensitization of the charge initiation a more sensitive initiation response of explosive is caused by the compression-shear loading under moderate proportion. Experimental analysis of rules and mechanism of the initiation response of explosive is presented in the paper.

进行了两类压剪加载实验:(1)利用石英的平面正碰撞产生压剪加载的实验,采用电磁质速法测试装药试件内部不同质点的运动情况,分析炸药装药中发生化学反应的可能性;(2)在压剪炮上采用平行倾斜碰撞产生压剪加载的实验,观测炸药装药爆炸的可能性。由实验可以看出:在亚爆轰状态的压缩加载应力条件下,剪切的联合作用对炸药的起爆起到敏化作用,适当比例的压剪加载造成更加敏感的炸药起爆响应。文中给出了起爆响应规律和响应机制的实验分析。

One dimensional planar compression-shear loading acting on the materials,which were cohered to the bact of quartz pieces was realized by using Y-cut a quartz crystals with their linearly elastic anisotropic dynamic response nature.Electric-magnetic particle velocity method was adopted to measure the movement of particles on different places in the materials.In the experiments,two-wave construction of compression-shear waves that propagated into the materials were observed clearly,the longitudinal and transverse particle velocity histories reflected fetures of dynamic response of materials under compression-shear loading.These results agreed with that from theoretic estimates on the whole .

利用Y—切石英晶体的各向异性动态响应材料特性,实现对粘接在石英晶体后表面的材料试件的一维平面复合压缩剪切加载。用电磁质速法测试试件中不同位置上的质点在压剪加载下的运动情况。从处于粘接界面上的量计所测纵向质速史和横向质速史,可以看到压剪波传入试件中的清晰的两波(QL波,QT波)结构,与理论估计基本相符;其它位置上量计的测试曲线亦反映了材料对压剪波传播的动态响应特点,可以看到剪切波的衰减规律。
