Harmonic response computation of poroelastic multilayered structures using ZPST shell elements

Abstract

This paper uses a multilayered shell element to compute the dynamic response of multilayered poroelastic structures such as car instrument panels, car floors, or car roofs. It is based on the P-order Shear deformation Theory with an added Zigzag function (ZPST). Biot’s theory is used to describe the poroelastic layer and standard couplings are realized between elastic and poroelastic layers. A method based on Padé approximants is also used in order to reduce the computation time. This acceleration technique enables to achieve fast frequency sweep computations compared to a standard direct method. Finally, numerical validations on plates and curved geometries are presented.
