"Computational Contact Mechanics: An Interplay between Finite Elements
and Optimization"
By
Abstract: Computational
contact mechanics problems can be notoriously difficult to solve and
optimization algorithms play a key role in addressing these problems in a
numerically reliable manner. In this presentation, I aim to underline the
advantages of a class of optimization algorithms known as interior point
methods. I will start with an introduction to the underlying variational
formulation of contact problems and then discuss a generic numerical
implementation in the framework
of the finite element method. I will subsequently highlight the role of optimization
in contact mechanics and discuss the steps leading to a particular interior
point algorithm. Finally, I will demonstrate the efficiency and the robustness
of the computational framework through various benchmark problems. The
presentation will be accessible to undergraduate students as well.
