Postbuckling and vibration of shear deformable flat and curved panels on a nonlinear elastic foundation
This study deals with the postbuckling and vibration behavior of flat and shallow curved panels resting on a Winkler linear/nonlinear elastic foundation. The considered plate/shell structural model is based on a higher-order shear deformable theory and encompasses a number of effects such as transverse shear, geometric nonlinearities and the initial geometric imperfection. Special emphasis is given to the influence played by Winkler's foundation moduli.
