Magneto-electro-thermoelastic interaction in unbounded media containing cylindrical cavities caused by a pulsed heat flux

This work applies the generalized magneto-electro-thermoelasticity model to investigate an isotropic thermoelastic medium with an infinite medium containing a cylindrical cavity, which is exposed to a uniform magnetic field along the axis. The cavity boundary is exposed to exponentially decaying pulse boundary heat flux. The solution is derived using an eigenvalues approach based on the Laplace transform technique applied to obtain solutions in the Laplace domain. Numerical inversions, performed through Fourier series expansions, enable the computation of displacement, temperature, radial and hoop stress, and induced electric and magnetic fields. Graphical representations illustrate these results.
