Abstract: | The stability of oriented glass-reinforced plastic plates resting on an elastic Winkler foundation is investigated using the theories of Timoshenko 2, 6] and Ambartsumyan 7], which permit the shear strains to be taken into account. The solution obtained is compared with the corresponding solution based on the classical Kirchhoff theory 8].L'vov Polytechnic Institute. Institute of Polymer Mechanics, AS LatSSR, Riga.
