二维编织C/SiC复合材料板疲劳损伤分析
|
摘要
为探索复合材料损伤的基本规律,首先,基于损伤力学,结合Tsai-Hill强度理论,提出了表征二维编织C/SiC复合材料损伤各向异性的损伤演化方程;然后,在商业有限元软件ANSYS环境中进行了二次开发,形成了考虑材料刚度随损伤折减的损伤模拟程序;其次,对二维编织C/SiC复合材料板模型进行了损伤模拟分析,结果表明材料损伤过程中应力与损伤度对单元破坏起共同作用;最后,对损伤演化方程的形式提出了讨论与改进,并通过模拟计算揭示了复合材料在损伤驱动力及材料特性作用下损伤呈现各向异性演化的特征,说明材料各向异性损伤是其材料特性及受载形式产生的必然结果。
To explore the basic laws of composite damage,first,based on damage mechanics,combined with Tsai-Hill criterion of strength,a damage evolution equation that can characterize the damage anisotropy of2 D braided C/SiC composites was proposed. Second,a damage simulation program considered material stiffness reduction depend on the damage degree,as an add-on function,was developed and inserted in the commercial finite element software ANSYS environment. Third,the damage evolution of the 2 D braided C/Si C composite plate model was simulated,and the result shows stress and damage degree have coupling effects on the element damage during the damage process. Finally,the form of damage evolution equation is discussed and improved,and the anisotropic characteristics of damage evolution under the material property and the action of damage driving force is revealed by analog computation,indicating that the material anisotropy damage is the inevitable result of its material properties and loaded form.
