The script for fast simulation model is developed considering the material nonlinearity and contact nonlinearity via Tcl/Tk language, the dent resistance is calculated with the Abaqus software. The structure for the variable conditions is optimized with the simplified script parameters. The results show that the present optimization method of whole process for solving the dent resistance for variable conditions is quick, efficient and accurate %K 可变工况 %K 抗凹性 %K 优化方法 %K 全流程< %K br> %K ABAQUS %K dent resistance %K efficiency %K finite element method %K flowcharting %K mesh generation %K optimization method %K variable conditions %K whole process %U http://journals.nwpu.edu.cn/jxkxyjs/CN/abstract/abstract6022.shtml
