A boundary element solution is developed for the analysis of thin elastic clamped plates of any shape resting on a Pasternak-type elastic foundation. The plate may have holes and it is subjected to concentrated loads, line loads, and distributed loads. The analysis is complete, i.e., deflections, stress resultants, subgrade reactions, and reactions on the boundary are evaluated. Several numerical examples are worked out and the results are compared with those available from analytical solutions. The efficiency of the BEM is demonstrated and discussed.

The problem of the effect of a normal harmonic force on a porous beam in a 3D formulation is solved using the boundary-element method. A homogeneous fully saturated elastic porous medium is described using Biot’s mathematical model. The effect of the porosity and permeability parameters on the deflection of the beam and the distribution of pore pressure over the beam thickness is investigated. The comparison of the boundary-element solution with a 2D numerical-analytical one is given.
