摘要
玻璃纤维增强复材(GFRP)圆管构件以良好的绝缘性能在电力工程中得到广泛应用。针对由内向外[0_(4)/90/0_(4)/90/0_(2)]缠绕成型的GFRP圆管构件,建立反映各向异性纤维铺层的有限元模型,采用Hashin失效准则和Matzenmiller-Lapczyk损伤演化模型开展了其在轴压下的性能仿真,揭示其随荷载增大的渐进损伤和应力分布规律,获得的构件力学行为与试验结果吻合,表明该数值仿真方法可有效反映纤维缠绕GFRP圆管的力学特征。
The glass fiber reinforced polymer(GFRP)circular members have been extensively applied in power engineering because of its good insulation performance.A finite element model reflecting the anisotropy of GFRP fiber sheets was constructed for GFRP pipes by filament winding at alternate angles of 0°,90°,0°,90°and 0°from inside to outside.The Hashin failure criterion and Matzenmiller-Lapczyk’s damage evolution model were used in the numerical simulations for pipes subjected to axial compression.The evolution rules of damage and stress were revealed.The mechanical properties reflected in the simulation were in agreement with that of tests,which indicated that the numerical simulation method was capable of reflecting the mechanical characteristics of the GFRP pipes of the filament winding method.
