BOUNDARY-ELEMENT METHOD FOR DYNAMIC POROELASTIC AND THERMOELASTIC ANALYSES

A boundary element method is developed for transient and time harmonic analysis of problems in dynamic poroelasticity and generalized thermo elasticity, involving bath two- and three-dimensional geometries. Lapl ace domain infinite space fundamental solutions are employed to produc e a formulation that requires only surface discretization. Consequentl y, the resulting algorithm provides an attractive alternative to exist ing volume-based methods, particularly for media of infinite extent. D etails of the formulation and numerical implementation are presented. Several applications are included to validate the method and to emphas ize certain aspects of the dynamic theory.
