Behavior of Contact (In ANSYS)

In   ANSYS,   the   contact   is  generated   by   pair.  For   the   point-surface   contact,   the   “point”   is  contact and the “surface” is target. For surface-surface contact, both contact and target are surfaces   and   they   have   to   be   specified   which   surface   is   contact   and   which   is   target.   No matter it’s point-surface contact or surface-surface contact, as soon as they are identified, they are then one pair.One can not exist without the other.

For the surface-surface contact, it is the first step to specify which is contact surface and which is target surface. Normally,    convex    surface   is  chosen    as  contact   and concave as target. Also when the size of one body in contact compared to another one is very small and then the large surface is chosen as target.  There are several kinds of contact used in ANSYS: frictional, frictionless, rough, bonded, no separation and so on. Contact surface has different types of behavior according to different characteristics of contact.
