Abstract
- In this paper, a boundary element formulation for non-conforming
contact problems, with the consideration of elastoplasticity, is presented. In order
to solve the contact problem, a direct constraint technique is employed. Friction
between the bodies is taken into account, and the materials may have different
elastoplastic properties. An initial strain BEM formulation is used to study the
elastoplastic problem. The material is assumed to obey the Von Mises yield cri-
terion with its associated flow rule.
An incremental loading technique is proposed, which enables to follow accurately
the loading history of the problem. An example of a cylinder on a flat foundation
is presented.
Introduction
A contact problem is of the non-conforming type, if the surfaces of the bodies
coming into contact do not ha
