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.
