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_AUTOMATIC_SURFACE_TO_SURFACE (a3) 是一种推荐的接触类型,因为在碰撞模拟中,由于模型经历了大变形,因此不能总是预测零件相对于彼此的方向。如前所述,自动接触会检查壳单元任一侧的穿透情况。 对于金属成形模拟,接触类型…… *CONTACT_FORMING_SURFACE_TO_SURFACE (m 3) 是可用的,但通常不用于单向成形接...

meshes. In the case of shell elements, automatic contact types determine the contact surfaces by projecting normally from the shell mid-plane a distance equal to one-half the ‘contact thickness’. Further, at the exterior edge of a shell surface, the ...

The device described utilizes a simple low-cost and robust mechanical design combined with software to interpret sensory data to measure the contact position of a normal force applied on a planar surface. The high-level interpretation method for this system enables automatic determination of contact ...
