Micro Abstract:
We suggest a computational framework combining the extended finite element method (X-FEM) with the mortar integration for domain-tying and contact problems. We formulate interface conditions between a finite element surface and a virtual surface, passing at any location of another FE mesh (level set). The integration of the internal work employs the X-FEM. The tying or contact constraints are satisfied in the mortar sense. The aimed applications include a structural zoom and wear simulation.
