Regularity and Stabilization of Magneto-Elastic Systems
We consider the mathematical model for a plate in a bounded reference configuration \(\Omega \subset \mathbb {R}^n\), first with \(n=2\), which is interacting with \(n=2\) magnetic fields. The latter have a damping effect. It will be shown that the arising system generates an analytic semigroup and that the estimated exponential decay rate tends to zero if the n constant directing magnetic vectors tend to become linearly dependent. Then, an analogous model for \(n=3\) will be considered. In the case that there are less than n magnetic fields we prove the strong stability exemplarily for cubes.
期刊介绍:
The Applied Mathematics and Optimization Journal covers a broad range of mathematical methods in particular those that bridge with optimization and have some connection with applications. Core topics include calculus of variations, partial differential equations, stochastic control, optimization of deterministic or stochastic systems in discrete or continuous time, homogenization, control theory, mean field games, dynamic games and optimal transport. Algorithmic, data analytic, machine learning and numerical methods which support the modeling and analysis of optimization problems are encouraged. Of great interest are papers which show some novel idea in either the theory or model which include some connection with potential applications in science and engineering.
