摘要
为研究无限长横观各向同性磁电弹圆柱中轴向对称压缩波的传播,考虑16种边界条件,得出广义频散方程,并讨论不同边界条件下波的频散特性。数值结果表明边界条件对磁电弹圆柱中轴向对称压缩波的传播特性有着显著的影响。
In this paper the propagation properties of axisymmetric compression wave in an infinite and transversely isotropic magneto-electro-elastic cylinder are investigated. The magneto-electro-elastic materials are assumed to possess hexagonal （6mm） symmetry. The generalized Poehhammer frequency equation is derived and the frequency spectrum curves under possible sixteen sets of boundary conditions are plotted. Numerical results show that boundary conditions have obvious and different influences on the propagation properties of axisymmetrie compression wave in a magneto-electro-elastic cylinder.
