     According to the basic failure modes in 2-Directional (2-D)carbon/carbon composite laminates,namely matrix cracking,delamination,fiber breakage and debonding,the research performance of the failure mechanisms in family and abroad under tensile load,shear load and uniaxial compression load have been summarized respectively. Some failure analysis methods at present for C/C laminated composite have also been given in this paper,which would be of general significance to its mectanical capacity.

  shear load
A plane of weakness is included in the model and this plane is subjected to increasing shear load while the normal load across the plane is held constant.
      
In conjunction with shear load stiffness, the normal load stiffness, often neglected, is shown to have a considerable effect on the stick-slip process -its presence or absence and its characteristics.
      
The shear modulus and elastic moduli are calculated as functions of the shear load and the degree of crystallization.
      
It is shown that under a constant shear load the shear strain increases with crystallization.
      
A closed form solution to the second order elasticity problem, when an isotropic compressible elastic half-space undergoes a deformation owing to a non-uniformly distributed shear load, is presented.

The paper deals with a method to restrict dilation of the clay course and prevent it from being sgueezed out under shearing stress when sandstone with weak intercalation is tested.The method of measuring stiffness parameters under normal load and shearing stress ( Kn and Ks ) is also being investigated.As a result of avoiding the relaxation dilation and disturbance of the filling materials, rock with weak intercalations is enabled to sustain larger loads normally applied on it. The data thus obtained more correctly reflected characteristics of the rock under compression normally applied and relationship of shearingstress versus displacement. A peak value of strength is manifested and residual strength is observed in the most cases.The method recommended by authors to restrict dilation of clay course by a special frame and bolts and to dose the shear zone to be tested by means of foaming plastics, has been obtaining good results. However in order to get stable displacement values under constant shearing load, it is necessary to use facilities to keep the pressure stable during the test.

本文说明在沙页岩地层上进行软弱夹层剪切试验时,采用了限制夹泥膨胀和防止夹泥受载挤出的措施.并研究了合理测定法向刚度系数(K_n)和剪切刚度系数(K_s)的方法. 由于防止了夹泥松弛,膨胀和结构扰动,提高了夹泥层的法向加载能力.正确地反映了法向载荷下的压缩特性和剪应力位移曲线.可以看到明显的峰值强度,并在绝大多数情况下获得了残余强度. 作者推荐的外锚筋固定法限制夹泥膨胀,用聚脂泡沫塑料板封闭剪切缝,效果甚为显著,但是为获得剪切载荷下的位移稳定值,需要增设稳压设备.

The destructive fracture a britlle rock undergoes in a fracture test has been explained,as a result of shear load.According to the author's experiment,however,the fracture is regarded as due to the action of a traverse tensile stress,that is,a fracture due to tension.In accordance with such a mechanism,the authors make a theoretical analysis based on Griffith's Theorem to clarify their point of view.

脆性岩石在单向压应力作用下,进行抗压破坏试验,过去传统解释为剪切破坏。根据作者的实验观测,认为是张性破坏,即岩石的破坏是在拉应力作用下引起的,并根据 Griffith 强度理论进行了理论分析。
