Unformatted text preview: ith CONTA175 element and solved using Lagrange Multipliers method. • A 3-D model using HYPER58 with CONTA175 element and solved using Lagrange Multipliers method. In the 3-D case, a MESH200 element is used as the target face for the automatic generation of contact elements. The target surface is given a high contact stiffness (KN = 2000 MPa) to model a rigid surface and no contact stiffness is required to be specified while performing the solution using Lagrange Multipliers method.
