Computational settings used in ANSYS and the IPG-DDA for Example 2.

	ANSYS	IPG-DDA
Element	PLANE82	Constant stress element
Contact element	CONTA172 with TARGE169	—
DOFs per element	12	6
Number of elements	7812	7812
Total DOFs	93744	46872
Normal contact stiffness (N/m)
Shear contact stiffness (N/m)	ALM	6.9E7
Number of substeps	3	1

The normal contact stiffness is determined by the augmented Lagrangian method in ANSYS.
The normal contact stiffness equals the equivalent Young’s modulus under the plane strain condition in the IPG-DDA.
