Finite element approximations of Landau -

چکیده
This paper deals with nite element approximations of the Landau-Ginzburg model for structural phase transitions in shape memory alloys. The non-linear evolutionary system of partial diierential equations is discretized in time by nite diierences and in space by very simple nite elements, that is, the linear element for the absolute temperature and the Hermite cubic element for the displacement. Thus both the displacement and the strain are obtained directly. Error estimates for the fully discrete scheme are derived.

Nonlinear Finite Element Analysis of Bending of Straight Beams Using hp-Spectral Approximations
Displacement finite element models of various beam theories have been developed using traditional finite element interpolations (i.e., Hermite cubic or equi-spaced Lagrange functions). Various finite element models of beams differ from each other in the choice of the interpolation functions used for the transverse deflection w, total rotation φ and/or shear strain γxz, or in the integral form u...

متن کاملAnalysis and Approximation of the Ginzburg-Landau Model of Superconductivity
The authors consider the Ginzburg-Landau model for superconductivity. First some well-known features of superconducting materials are reviewed and then various results concerning the model, the resultant differential equations, and their solution on bounded domains are derived. Then, finite element approximations of the solutions of the Ginzburg-Landau equations are considered and error estimat...
