Modeling of thermo-electro-magnetic-elastic waves in a transversely isotropic circular fiber

摘要

In this article, wave propagation in a transversely isotropic thermo-electro-magneto-elastic circular fiber is studied. The equation of motion are formulated using the three dimensional theory of thermo-electro-magneto elasticity. The displacement, electric, magnetic and thermal potentials are introduced to uncouple the equations of motion. The frequency equations for both longitudinal and flexural modes of vibration are derived and the numerical results are plotted in the form of dispersion curves. The frequency equation of an electro-magneto-elastic circular fiber is derived by omitting the thermal field and the dispersion behavior of thermo-electro-magneto elastic and electro-magneto-elastic circular fiber is discussed in the form of comparison graphs.
