准确预测含分层损伤层合板的剩余压缩强度，对复合材料具有十分重要的意义。本文基于层合板一阶剪切理论，建立了一种考虑复合材料多种损伤的含分层层合板刚度退化模型，通过数值算例分析了分层屈曲临界载荷与材料强度极限的关系以及刚度退化对含分层层合板前后屈曲行为的影响。
Accurately predicting the residual compressive strength of delaminated laminates is very important for composites. In this paper, based on the first-order shear theory of laminated plates, a stiffness degradation model of composite laminated plates considering various damage of composite materials is established. By numerical examples, the relationship between the critical loads of layered buckling and the material strength limits and the stiffness degeneration Effect of Buckling Behaviors before and after Laminated Laminated Plates.
