An Introduction to the Unilateral Contact Problems in Mechanics

Raúl A. Feijóo, Hélio J. C. Barbosa


In this paper the unilateral contact problem within the elastostatic linear theory is presented. The problem is formulated as a variational inequality or as a constrained minimization problem. The accomplishment of approximate solutions is done using the finite element method and mathematical programming techniques. At last some numerical examples are shown.
