Axisymmetric buckling of Reddy circular plates on Pasternak foundation

Presented herein are the exact axisymmetric buckling solutions of Reddy cir cular plates on the Pasternak foundation and subjected to a uniform radial load. The boundary conditions of the circular plates covered in this study are (1) simply supported edges; (2) clamped edges; and (3) simply supported edges with elastic rotational restraints. The Reddy buckling solutions are expressed in terms of the corresponding well-known Kirchhoff buckling solu tions of circular plates without the elastic foundation. Sample buckling re sults of Reddy plates are also presented, which should be useful as benchma rk solutions for testing numerical solutions and techniques.
