In this note, we consider a Frémond model of shape memory alloys. Let us imagine a piece of a shape memory alloy which is fixed on one part of its boundary, and assume that forcing terms, e.g., heat sources and external stress on the remaining part of its boundary, converge to some time-independent functions, in appropriate senses, as time goes to infinity. Under the above assumption, we shall discuss the asymptotic stability for the dynamical system from the viewpoint of the global attractor. More precisely, we generalize the paper [P. Colli and K. Shirakawa, Attractors for the one-dimensional Frémond model of shape memory alloys, Asymptot. Anal. 40 (2004), 109-135]. First, we show the existence of the global attractor for the limiting autonomous dynamical system, then we characterize the asymptotic stability for the non-autonomous case by the limiting global attractor.

Abstract
In this note, we consider a Frémond model of shape memory alloys. Let us imagine a piece of a shape memory alloy which is fixed on one part of its boundary, and assume that forcing terms, e.g., heat sources and external stress on the remaining part of its boundary, converge to some time-independent functions, in appropriate senses, as time goes to infinity. Under the above assumption, we shall discuss the asymptotic stability for the dynamical system from the viewpoint of the global attractor. More precisely, we generalize the paper [P. Colli and K. Shirakawa, Attractors for the one-dimensional Frémond model of shape memory alloys, Asymptot. Anal. 40 (2004), 109-135]. First, we show the existence of the global attractor for the limiting autonomous dynamical system, then we characterize the asymptotic stability for the non-autonomous case by the limiting global attractor.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
