Wave propagation and uniqueness in magneto-elastodynamics (Q1077240)

In this work, using the method the authors developed in J. Elasticity 14, 163-174 (1984; Zbl 0547.73011), they studied the wave propagation and the uniqueness in magneto-elastic bodies. In order that a perturbation initially confined in a proper subset of an unbounded magneto-static solid, propagate with a finite speed, some sufficient conditions on the acoustic tensor and on the kinetic and magnetic fields are given. In addition to this, a strong uniqueness theorem is proved for regular solutions to the initial-boundary value problem of magneto- elastodynamics. This work might be interesting for those researchers working on wave propagation in conducting magneto-elastic bodies.
