Statics and dynamics of simply supported polygonal Reissner-Mindlin plates by analogy

摘要

Free and forced vibrations of moderately thick, transversely isotropic plates loaded by lateral forces and hydrostatic (isotropic) in-plane forces are analyzed in the frequency domain. Influences of shear, rotatory inertia, transverse normal stress and of a two-parameter Pasternak foundation are taken into account. First-order shear-deformation theories of the Reissner-Mindlin type are considered. These theories are written in a unifying manner using Tracers to account for the various influencing parameters.
