Cylindrical stress waves in poroelastic flat slabs

摘要

Biot's poroelastic theory is employed to study stress wave propagation in an infinite slab of arbitrary thickness. The frequency equation is obtained each for pervious and impervious surfaces for a non-dissipative medium. Appropriate numerical data is presented in the form of graphs and then results are discussed. Waves in a thin bar and in a semi-infinite slab are discussed as limiting cases.
