This study analyses the finite deformation and the bifurcation behavior plane strain bending of a bilayer with layers made of hyper elastic and incompressible of varga model. The bending solution is employed to investigate possible incremental bifurcations. The analysis reveals that a bilayered structure can behave in completely different way from the corresponding homogeneous plate. For a thick plate of varga material, for instance, the presence of a stiff coating strongly affects the bifurcation critical angle.
