Summary:

Isogeometric analysis is a computational mechanics technology which uses basis functions emanating from computer aided geometric design (CAGD), such as B-splines, NURBS, T-splines, subdivision surfaces, etc., instead of traditional C0-continuous Lagrange finite element interpolatory polynomials. It has been shown that isogeometric analysis provides more precise and efficient geometric representations, high accuracy combined with robustness, accurate derivatives and stresses, and the potential to integrate CAGD and analysis processes. This has opened the way to efficient and elegant solutions for various problem classes, among which computational contact mechanics is an outstanding example. We have recently initiated a systematic study of contact problems with NURBS-based isogeometric analysis for thermomechanical contact problems with and without friction through numerically robust mortar approaches. Our present efforts are concentrated towards the enhancement of mortar approaches for isogeometric analysis for various contact and interface problems.

This is a research thrust area (RTA3) of CMML. Please contact Prof. Temizer for current positions available.
