WebFor contact pairs, you can specify the penalty method as an alternative to the default kinematic enforcement method. When the penalty method is chosen for enforcing … WebJul 13, 2024 · Penalty vs Lagrange Methods. There are two basic methods of contact formulation in ANSYS: Penalty based and Lagrange Based. The two types of methods differ in how the contact interaction (between the contact and target surfaces) is treated mathematically. With the Normal Lagrange method, the contact status is a step function.

WebGeneral contact is a more versatile method to deal with contact since contact between disconnected regions of the bodies can be described with a single interaction. Contact pair requires more careful definition of contacting surfaces and has many restrictions on the types of surfaces involved. Fig 2-General contact and contact pairs in Abaqus. 3.
