FRICTIONLESS CONTACT WITH BEM USING QUADRATIC PROGRAMMING

The paper presents a computational formulation for the frictionless contact of an elastic body with a rigid surface, treated as an optimization problem. The contact conditions, along with the equilibrium equations of the elastic solid expressed as boundary integral equations, are employed together to define the objective functions and the corresponding constraints. Three distinct objective functions are considered, and each is reduced to quadratic form. A number of numerical examples involving contact regions of arbitrary geometric configurations are presented. The details of the study are described. It is noted that the formulations will be useful for the economical solution of large contact problems with multiple contact regions.
