CONSTITUTIVE RELATIONS RESEARCH FOR CRACKED COMPOSITE LAMINATES WITH ANISOTROPIC LAYERS

摘要

摘要: 本文作者对含非正交各向异性铺层的约束开裂复合材料层板,提出用分解刚度的方法建立本构关系;给出分解后耦合问题的控制微分方程;作为特例,研究了(-θ_m/90_n/θ_m)_s开裂层板的刚度衰减.

Abstract: Anidea of stiffness partition is proposed to develop the constitutive relations foracracked composite laminate with anisotropic constraint layers. The governing equation of the coupled stiffness problem is derived after partition. As an example, the stiffness degradation for cracked(-θ_m/90_n/θ_m)_s laminates is studied.
