在接触类型的面前,最小网格尺寸决定计算时间,那简直就是笑话,别问我怎么知道的,亲测!!!),常用的接触类型大致分为以下几种,自动单面接触(CONTACT_AUTOMATIC_SINGLE_SURFACE),自动面面接触(CONTACT_AUTOMATIC_SURFACE_TO_SURFACE_ID),自动点面接触(*CONTACT_AUTOMATIC_NODES_TO_SURFACE_ID/Contact...

*CONTACT_ERODING_NODES_TO_SURFACE (16) 如果从属表面的节点可能最终位于主表面之后,则应避免使用这些接触类型。这些非自动接触类型可能会或可能不会考虑壳厚度偏移(参见SHLTHK中*CONTROL_CONTACT)。如果壳厚度偏移处于非活动状态(默认),则来自公共域的旧节点到表面接触处理DYNA3D用于上面的接触类型 5 和 10,其中增量...
