采用电-热-热解耦合模型对碳纤维增强复合材料（CFRP）层合板在雷击下的损伤进行了分析，该模型由ABAQUS/Standard有限元程序与用户自定义子程序USDFLD和HEATVAL耦合实现。为明确雷电流波形参数对CFRP材料热/电性能的影响，对CFRP层合试件在不同雷电流波形下的损伤进行了试验和数值分析。结果表明，损伤体积与作用积分呈很强的对数关系，损伤受CFRP电性能的影响很大，而热导率的变化对损伤体积几乎没有影响。(C)2016爱思唯尔有限公司版权所有
The damage of carbon fiber reinforced polymer (CFRP) laminated composites under lightning strike is analyzed by coupled electrical-thermal-pyrolytic models, which is implemented by the ABAQUS/Standard finite element code coupled with user-defined subroutines USDFLD and HEATVAL. To clarify the effects of the lightning current waveform parameters and the thermal/electrical properties of CFRPs, the damages of CFRP laminated specimens under diverse lightning current waveforms are experimentally and numerically analyzed. The results reveal that the damage volume shows a strong logarithmic relationship with the action integral, and that the damage is strongly governed by the electrical properties of CFRPs, though thermal conductivity variation barely affects the damage volume.
