Lagrangian-Hamiltonian formalism for cocontact systems
In this paper we present a unified Lagrangian–Hamiltonian geometric formalism to describe
time-dependent contact mechanical systems, based on the one first introduced by K. Kamimura and
later formalized by R. Skinner and ...
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 ...
A mortar method combined with an augmented Lagrangian approach for treatment of mechanical contact problems
(Springer, 2014)
This work presents a mixed penalty-duality formulation from an augmented Lagrangian approach for treating the contact inequality constraints. The augmented Lagrangian approach allows to regularize the non differentiable ...
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 ...
Lagrangian reduction of nonholonomic discrete mechanical systems
(American Institute of Mathematical Sciences, 2010-03)
In this paper we propose a process of lagrangian reduction and<br />reconstruction for nonholonomic discrete mechanical systems where the action of a continuous symmetry group makes the configuration space a principal ...
