Abstract: In the continuum structural mechanics framework, a unilateral contact condition between two flexible bodies does not generate impulsive contact forces. However, finite-dimensional systems, derived from a finite element semi-discretization in space for instance, and undergoing… read more here.

Abstract: Abstract We study the linear finite element approximation of the elasticity equations with and without unilateral friction contact (of Tresca type) conditions in a polygonal or polyhedral domain. The unilateral contact condition is weakly imposed… read more here.

Abstract: Unusual distributions of contact dermatitis often lead to identification of the offending agent. We present a case of unilateral dermatitis of the chest developing in a patient with a history of allergy to metal. A… read more here.
