Abstract
Despite to great potential of poroelastic materials, the number of dynamic investigations on poroelastic materials is limited., in this article, the influence of humid-thermal environment on bulk wave propagation behavior of sigmoid poroelastic shells resting on sinusoidal elastic foundation is examined. In order to calculate the effective properties of poroelastic shell structure made of titanium and alumina, the improved sigmoid power-law homogenization scheme is employed.
Kinetic relations of poroelastic shell structure are developed based on first-order shear deformable theory. Then, Hamilton’s principle has been implemented to obtain the governing equations and harmonic functions are utilized to solve the derived equations.
