An augmented lagrangian method to solve three-dimensional nonlinear contact problems
(Planta Piloto de Ingeniería Química, 2012-11)
A finite 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 ...
The boundedness of penalty parameters in an augmented Lagrangian method with constrained subproblems
(Taylor & Francis Ltd, 2012-12)
Augmented Lagrangian methods are effective tools for solving large-scale nonlinear programming problems. At each outer iteration, a minimization subproblem with simple constraints, whose objective function depends on updated ...
A relaxed constant positive linear dependence constraint qualification and applications

An augmented Lagrangian technique combined with a mortar algorithm for modelling mechanical contact problems
(Wiley, 2013-01)
A finite element formulation for three dimensional (3D) contact mechanics using a mortar algorithm combined with a mixed penalty-duality formulation from an augmented Lagrangian approach is presented. In this method, no ...
New Optimization Algorithms for Structural Reliability Analysis
(TECH SCIENCE PRESSNORCROSS, 2012)
Solution of structural reliability problems by the First Order method require optimization algorithms to find the smallest distance between a limit state function and the origin of standard Gaussian space. The Hassofer-L ...
Numerical solutions for frictional contact problems based on a mortar algorithm with an augmented Lagrangian technique
(Springer, 2015-12)
This work presents a frictional contact formulation to solve three-dimensional contact problems with large finite displacements. The kinematic description of the contacting bodies is defined by using a mortar approach. The ...

Coevolutionary Genetic Algorithm Based on the Augmented Lagrangian Function for Solving the Economic Dispatch Problem
(2015-10-01)
This paper proposes a coevolutionary augmented Lagrangian method (AGCE) for solving the classic economic dispatch problem. This problem becomes non-convex and non-differentiable if valve-point loadings effects are considered ...
Validation of an augmented lagrangian algorithm with a Gauss-Newton Hessian approximation using a set of hard-spheres problems
