Hemming is an important joining method whereby external Al-Mg-Si automotive body sheets are bent by 180° around the internal panels.Large strains associated with the bending can lead to failures such as cracks and/or high surface roughness.The large strain needs to be distributed to a certain depth (from the apex) so as to achieve a successful hemming.

地震易损性分析是地震灾害分析的重要内容,可以比较全面地评价结构的抗震性能,因此,快速有效地获得结构的地震易损性非常重要.本文以一RC框架为对象,同时考虑结构材料和地震动的不确定性,以中心复合设计法建立试样样本对,用OpenSees软件建模并对样本进行非线性分析,建立了基于高维模型表达的结构近似模型,继而采用蒙特卡洛模拟得到结构易损性曲线;并且将结果与响应面法得到的易损性曲线进行比对.分析结果表明:
