我在用ABAQUS对工程陶瓷(我选的是氧化锆)进行单颗磨粒的磨削仿真时,遇到好多问题,在这里请大家帮忙。$ x4 R. K% H5 x$ s 1)氧化锆材料改选哪种本构模型?我看了好多资料,我的这个仿真其实跟切削仿真比较类似,但好多切削仿真对是对金属的切削,选的本构模型是J-C本构模型,但这个模型貌似只适用于金属材料。3 v i* O# S" d/ [# K1 ~/ v 2)我查看的好多切削仿真中,工件通常被分为三部分:未变形切屑、分离线、工件基体,我想知道这三者之间需要相互之间固定死吗?需要进行哪些设置?有些仿真只是在接触性质处有些设置,但我还不大明白 0 t) w8 S% o0 R4 e1 f6 c8 t3)我的仿真结果经常由于单元的过度变形而出错,我该怎么解决这个问题?+ F$ L; L2 }9 J" \
