A Three-field Augmented Lagrangian Formulation of Unilateral Contact Problems with Cohesive Forces
We investigate unilateral contact problems with cohesive forces, leading to the constrained minimization of a possibly nonconvex functional. We analyze the mathematical structure of the minimization problem. The problem is reformulated in terms of a three-field augmented Lagrangian, and sufficient conditions for the existence of a local saddle-point are derived. Then, we derive and analyze mixe...
متن کاملAn Augmented Lagrangian Method to Solve Three-dimensional Nonlinear Contact Problems
A nite element formulation to deal with the friction contact problem between an elastic body and a rigid foundation is presented. An augmented Lagrangian method, which incorporates two Lagrange multipliers and a slack variable in the constraint equation, is developed. In this method, the solution is achieved through a Newton-Raphson monolithic iterative strategy and leads to simple implementati...
متن کاملMechanical design problems with unilateral contact
We formulate two problems of optimal design for mechanical structures in unilatéral contact the truss topology problem and the matenal design problem for elastic bodies In both cases we consider gênerai multi-load formulations, wherefor each load-case we may have different set of contact constraints (ngid obstacles) We show that both problems (after discretizatwn of the latter one) can be rewri...
متن کاملA symmetric boundary integral formulation for cohesive interface problems
An incremental symmetric boundary integral formulation for the problem of many domains connected by non-linear cohesive interfaces is here presented. The problem of domains with traction-free cracks and/or rigid connections are particular instances of the proposed cohesive formulation. The numerical approximation of the considered problem is achieved by the symmetric Galerkin boundary element m...
متن کاملLagrangian Formulation of the Electromagnetic Field
This paper will, given some physical assumptions and experimentally verified facts, derive the equations of motion of a charged particle in an electromagnetic field and Maxwell’s equations for the electromagnetic field through the use of the calculus of variations.
