摘要

摘要: 针对复合材料开口结构在压缩载荷下损伤扩展问题,采用累积损伤方法,对典型铺层方式下层合板压缩强度和损伤扩展规律进行了数值模拟研究。研究结果表明:不同铺层方式对含孔层合板的强度特性和损伤扩展形式有显著影响。在此基础之上,进一步研究了不同开口尺寸、不同铺层比例对层合板压缩强度的影响。

Abstract: The damage evolutions of compression loaded composite laminates with circle cutout were simulated based on the three-dimension progressive damage model.Good agreement was found between the analytical and experimental results.The results showed that the ply stacking-sequence could significantly influence the damage propagations of each layer.Based on the validated finite element model,the influence of ply stacking-ratio on the strength of composite laminates was analysed.
