Green-Naghdi (G-N) theory of thermoelasticity is employed to study the deformation of micropolar thermoelastic solid with voids considering the influence of varions sources acting on the plane surface.The normal mode analysis is used to obtain the analytical expressions of the displacement components,force stress,coupled stress,variation of volume fraction field and temperature distribution.The computed results are presented graphically when the volume source is applied.Comparisons of type Ⅱ and type Ⅲ with and without micropolarity effect are made with the results predicted in the context of (G-N) theory.
