Vibration of thermomechanically loaded flat and curved panels taking into account geometric imperfections and tangential edge restraints

Abstract A study of the effects played by tangential edge constraints on the vibrational behavior of single/multilayered doubly-curved shallow panels subjected to complex thermomechanical loading systems acting in the pre/postbuckling regimes is presented. In addition, effects related to the transverse shear and initial geometric imperfections are incorporated and their influence is highlighted. Numerical illustrations based on a higher-order theory underline the strong influence played by the above mentioned effects, in general, and by tangential-edge restrains on the alleviation of the intensity of the snap-through buckling, its delay and suppression, in particular. 1997 Elsevier Science Ltd.
