Abstract

In the present paper, the qusi-static behavior of a composite beam with saturated porous core is investigated. Dimensional reduction method is employed to calculate equivalent stiffnesses of the composite beam cross section with considering warping effects. Dimensional reduction is a method in which, 3-D elasticity problem is reduced to 1-D beam analysis by calculating in and out of plane cross sectional 3-D warpings with polynomial functions. The porous core is saturated with a viscose fluid and it only allows fluid flow in axial direction. Owing to presence of the viscose fluid, material behavior is dependent on time. Porous beam governing equations are modified using equivalent stiffnesses and are solved analytically. Results are obtained for a simply supported beam under suddenly applied load. The results suggest significant changes in composite beam behavior. Such models are promising for use in advanced composite structures.
