本文在文献的基础上,考虑了纤维和基体本构关系的非线性,讨论了正交铺层和±θ角铺层的情况,采用小弹-塑性形变理论、复合材料微观力学的复合定律和线性稳定理论。得到了求解复合材料园柱曲板在轴压下非线性弹性失稳时临界载荷的算式。给出了算例和讨论及测定单向复合材料层片非线性弹性常数的方案。
Based on the literature, the nonlinearity of the constitutive relation between fiber and matrix is considered. The situation of orthogonal ply and ± θ angle ply is discussed. By using the theory of small elastic-plastic deformation and the composite law of micro mechanics of composites Linear stability theory. The formula of critical load for solving nonlinear buckling of composite curved column under axial compression was obtained. An example is given and the scheme to discuss and measure the nonlinear elastic constants of unidirectional composite laminates is given.
