摘要

摘要: 发展了湿/热/静力耦合条件下复合材料结构渐进损伤仿真方法,考虑复合材料力学性能的随机分布特性建立有限元模型,改进了湿热条件下复合材料本构关系,以Hashin准则、最大应力准则作为失效判据,完整仿真了不同湿热条件、不同载荷类型作用下复合材料开孔层合板从损伤起始至最终失效的损伤演化全过程,极限强度预测结果与相应试验结果的误差在10%以内,验证了仿真分析方法的有效性.湿热效应对损伤起始和演化的影响表明:由于湿热条件作用,相对于室温干态而言,复合材料开孔层合板的损伤起始的时间提前、所需载荷降低,极限强度和极限应变减小.

Abstract: A tracking method of progressive damage on composite structure under the hydro/thermo/mechanical coupled condition was developed. The finite element model was built considering the random distribution of mechanical properties. Constitutive relation of composite material under hygrothermal condition was improved. Taking Hashin criteria and maximum stress criteria as failure criterion, the whole damage process from initial damage to ultimate failure of composite open hole laminates was simulated completely by this method under different hygrothermal conditions and different load types. The errors between ultimate strength prediction results and experimental results are less than 10%, so the effectiveness of this method is verified. The hygrothermal effect on the damage initiation and evolution shows that initial damage appears earlier and the ultimate strength and ultimate strain decreases under hygrothermal condition compared with room temperature dry condition.
