Definition of the initial problem
Grahic Jump Location
Equivalent method when the ratio of thickness ε tends towards 0. (a) Case 1: Elastic body and thin elastic layer. Contact algorithm uses a forward incremental Lagrange multiplier method. (b) Case 2: Elastic body and rigid body. Contact algorithm uses a penalty method with a specific contact law.
