Global Existence and Asymptotic Behavior in Nonlinear Thermoviscoelasticity

نویسنده

چکیده

We study global existence, uniqueness, and asymptotic behavior, as time tends to infinity, of weak solutions to the system of nonlinear thermoviscoelasticity. Various boundary conditions are considered. It is shown that for any initial data (u0 , v0 , %0) # L _W 1, _H 1 there is a unique global solution (u, v, %)=(deformation gradient, velocity, temperature) such that u # C([0, ], L ), v # C((0, ), W 1, ) & L ([0, ), W 1, ), % # C([0, ), H). The constitutive assumptions for the Helmholtz free energy include the models for the study of phase transition problems in shape memory alloys. 1997 Academic Press

Asymptotic behavior of a system of two difference equations of exponential form

In this paper, we study the boundedness and persistence of the solutions, the global stability of the unique positive equilibrium point and the rate of convergence of a solution that converges to the equilibrium $E=(bar{x}, bar{y})$ of the system of two difference equations of exponential form: begin{equation*} x_{n+1}=dfrac{a+e^{-(bx_n+cy_n)}}{d+bx_n+cy_n}, y_{n+1}=dfrac{a+e^{-(by_n+cx_n)}}{d+...

Global Existence and Asymptotic Behavior of Solutions for Some Nonlinear Hyperbolic Equation

The initial boundary value problem for a class of hyperbolic equation with nonlinear dissipative term u tt − n i1 ∂/∂x i |∂u/∂x i | p−2 ∂u/∂x i a|u t | q−2 u t b|u| r−2 u in a bounded domain is studied. The existence of global solutions for this problem is proved by constructing a stable set in W 1,p 0 ΩΩ and show the asymptotic behavior of the global solutions through the use of an important l...

für Mathematik in den Naturwissenschaften Leipzig Global Existence for a Nonlinear System in Thermoviscoelasticity with Nonconvex Energy

A three-dimensional thermoviscoelastic system derived from the balance laws of momentum and energy is considered. To describe structural phase transitions in solids, the stored energy function is not assumed to be convex as a function of the deformation gradient. A novel feature for multi-dimensional, nonconvex, and non-isothermal problems is that no regularizing higher order terms are introduc...
