4) craze density
银纹密度
1.
At the same time, through the microscope test of surface, the effect on craze density by strain rate has been investigated as wel.
同时通过表面银纹显微镜观察实验 ,研究了应变率对银纹密度的影响。
5) Crack density
裂纹密度
1.
The crack distance and crack density were the n calculated while taking the residual thermal effect into account, with the res ults fitting perfectly with the existing experimental values.
基于剪滞理论 ,建立了一个分层剪滞分析模型 ,研究了正交叠层板在拉伸荷载作用下 ,90°层发生横向基体多级开裂的问题 ,求得了计及固化残余热效应影响的裂纹间距和裂纹密度 ,所得结果与现有实验结果较吻合 ,进一步证实了所提模型和分析方法的正确性和可靠性 。
2.
Using the finite sublayer shearlag model, this paper studies the multiple cracks of transverse matrix in crossply laminates under uniaxial tension, derives the relationship between the transverse crack density and applied stress, and obtains the results which are relatively close to the existing test values.
采用有限子层剪滞分析模型，研究了受轴向拉伸的复合材料正交叠层板横向基体多重断裂问题，导出了裂纹密度与施加应力的关系，得到了与现有实验较为接近的结果。
3.
Because the formulas are expressed as a function ofcrack density,the relation between crack density and stresses in the damage zone is constructed so as to predict the stiffness degrada- tion directly from the stress distribution in damage zone.
对约束开裂复合材料层板给出随裂纹密度变化的刚度衰减公式。
