This chapter will investigate the contact interaction physics and contact properties implemented with both Abaqus standard and explicit solvers. Contact definition is a source of high nonlinearity in FEA model and therefore, a good understanding regarding how to make a correct representation of physics ...

definition the program computes the distance of the slave nodes from the master surface and takes into account this surface normal - so you will get always a overclosure for separated surfaces if you choose the wrong direction I have noticed that you are modelling micro-indentation in ABAQUS. I...
Contact interactions for contact pairs and general contact are defined in ABAQUS [1.29] by specifying surface pairings and self-contact surfaces. General contact interactions typically are defined by specifying self-contact for the default surface, which allows an easy, yet powerful, definition of cont...
