Abstract

The dynamic behavior of inelastic thick plates is investigated. A 36-degree-of-freedom rectangular finite element, which includes shear deformation effects and adequately represents associated boundary conditions, is developed. The accuracy of the element is established through comparison with available results for static deflection and natural frequencies. The yield surface is considered as a function of in-plane and transverse shear stresses. It is found that the contribution of the transverse shear stresses upon the plastic deformations is relatively small. The response of simply supported and clamped thick plates lo impulse excitation is found and the results are compared with those obtained from thin plate theory.
