Convergence of relaxation schemes to the equations of elastodynamics
نویسندگان
چکیده
We study the effect of approximation matrices to semi-discrete relaxation schemes for the equations of one-dimensional elastodynamics. We consider a semi-discrete relaxation scheme and establish convergence using the Lp theory of compensated compactness. Then we study the convergence of an associated relaxation-diffusion system, inspired by the scheme. Numerical comparisons of fully-discrete schemes are carried out.

A Stress Relaxation Model with Polyconvex Entropy Function Approximating Elastodynamics
The equations of polyconvex elastodynamics can be embedded to an augmented symmetric hyperbolic system. This property provides a stability framework between solutions of the viscosity approximation of polyconvex elastodynamics and smooth solutions of polyconvex elastodynamics. We devise here a model of stress relaxation motivated by the format of the enlargement process which formally approxima...

The embedding of the equations of polyconvex elastodynamics to an augmented symmetric hyperbolic system provides in conjunction with the relative entropy method a robust stability framework for approximate solutions [18].

متن کاملStructural Properties of Stress Relaxation and Convergence from Viscoelasticity to Polyconvex Elastodynamics
We consider a model of stress relaxation approximating the equations of elastodynamics. Necessary and sufficient conditions are derived for the model to be equipped with a global free energy and to have positive entropy production, and the resulting class allows for both convex and non-convex equilibrium potentials. For convex equilibrium potentials, we prove a strong dissipation estimate and t...
متن کاملAPPROXIMATION OF STOCHASTIC PARABOLIC DIFFERENTIAL EQUATIONS WITH TWO DIFFERENT FINITE DIFFERENCE SCHEMES
We focus on the use of two stable and accurate explicit finite difference schemes in order to approximate the solution of stochastic partial differential equations of It¨o type, in particular, parabolic equations. The main properties of these deterministic difference methods, i.e., convergence, consistency, and stability, are separately developed for the stochastic cases.
