Some remarks on growth and uniqueness in thermoelasticity.
The energy method for elastic problems with non-homogeneous boundary conditions
In this paper we propose the weighted energy method as a way to study estimates of solutions of boundary-value problems with non-homogeneous boundary conditions in elasticity. First, we use this method to study spatial decay estimates in two-dimensional elasticity when we consider non-homogeneous boundary conditions on the boundary. Some comments in the case of harmonic vibrations are considered as well. We also extend the arguments to a class of three-dimensional problems in a cylinder. A section...
Some theorems of Phragmen-Lindelof type for nonlinear partial differential equations.
The present paper studies second order partial differential equations in two independent variables of the form Div(ρ|u,|u,, ρ|u,|u,) = 0. We obtain decay estimates for the solutions in a semi-infinite strip. The results may be seen as theorems of Phragmen-Lindelof type. The method is strongly based on the ideas of Horgan and Payne [5], [6], [8].
A note on prestressed thermoelastic bodies.
This note is concerned with the ill-posed problem for prestressed thermoelastic bodies. Under suitable hypotheses for the thermoelastic coefficients, the domain and the behavior of solutions at infinity, we prove uniqueness of the solutions. We also obtain some estimates for the solutions related with the initial condition.
Instability in semi-infinite strips of solutions of linear systems.
The present paper is devoted to study the behaviour at infinity of some solutions of non autonomous and non homogeneous second order linear systems in semi-infinite strips.
A short note on incremental thermoelasticity.
The equations of classical thermoelasticity have been extensively studied [1], [2], [3], [4], [5]. Only more recently the equations when the initial state is at non-uniform temperature have been established [6], and a well-posedness theorem proved by the author and C. Navarro for these equations [7]. Our goal here is to make a brief comment about dissipation in this last case of an initial state with non-uniform temperature.
