摘      要：The main objective of this research is to investigate the hygroelastic behavior of a non-homogeneous circular plate made up of porous metamaterial resting on an auxetic material *** mechanical properties of the main plate,as well as moisture concentration,vary as an exponential function in the transverse ***’s ratio is *** elastic supporting medium is developed by considering the structurestructure *** on the linear hygroelasticity theory,the governing state equations in terms of displacements and moisture concentration are *** first,the Fickian equation is solved to compute the nonlinear distribution of moisture through the plate thickness,and then the state equations are semi-analytically solved using the statespace(SS)method and the differential quadrature(DQ)rule to predict the elastic field quantities.A comprehensive parametric analysis is accomplished to elucidate the effects of key parameters on the steady-state response of the plate under the mechanical and hygral loads.
