Algorithms for the analysis of 3D finite strain contact problems
From the constraint imposition aspects in 3D to friction regularization, various ideas are exposed in this paper. A variation of the Rockafellar Lagrangian is proposed which results in continuous second-order derivatives if Lagrange multiplier estimates are greater or equal than one. This fact allows the adoption of a full second-order (i.e. Lagrange–Newton) method avoiding sequential unconstra...
متن کاملAdaptive Finite Element Analysis of Large Strain Elastic Response
Abatmet-Some basic studies and developments for adaptive procedures in large strain finite element analysis are presented an evaluation of higher-order elements, two pointwise indiitors for errors in stresses, a mesh generator for remeshing on the deformed contiffuration of the body, and a general mapping scheme for transferring solution variables across models. The methods discus4 constitute t...
متن کاملAn Isoparametric Finite Element Model for Large-Strain Elastostatics
This paper describes a simple finite element model for large-strain elastostatics. The realization of the model in a small-scale computer-code is described. The purpose of the model is to produce test problems for research on the application of penalty techniques in nonlinear elasticity. For this reason the code must balance the requirements of reasonable flexibility with those of computational...
متن کاملSoft metal constructs for large strain sensor membrane
Thin gold films on silicone display large reversible change in electrical resistance upon stretching. Eutectic liquid metal conductors maintain bulk metal conductivity, even upon extensive elongation. When integrated together, the soft metals enable multidirectional, large strain sensor skin. Their fabrication process combines thermal evaporation of thin gold film patterns through stencil mask ...
