标题: Abaqsu中,做单磨粒的二维磨削仿真,运行的时候会有警告Thermal contact between surfaces ASSEMBLY_SURF-CHIP-BOT and ASSEMBLY_SURF-JOINT-TOP is causing a 98.900% reduction in the time increment,然后计算的很慢,这是怎么回事? [打印本页]

最近在做单磨粒的二维磨削仿真,说白了也就是切削仿真,参照的是经典例题集3里面非稳态切削的例子,建模的时候分切屑层、连接层、工件共三层,不同的是,模型稍微有点变化主要是材料属性,刀具前角,还有模型尺寸,另外用的是J-C本构模型加shear damage,但是总出不来结果,具体见下图:运行的时候会有警告Thermal contact between surfaces ASSEMBLY_SURF-CHIP-BOT and ASSEMBLY_SURF-JOINT-TOP is causing a 98.900% reduction in the time increment,然后计算的很慢
