Resumo
This paper allows us to study the effect of the level of load conservativeness on the stability of circular plates. A stability analysis of thin and thick circular and annular plates structures subject to a combination of nonconservative tangential follower loads, using the dynamic criterion is performed. The initial tangent stiffness and mass matrices are obtained using the Rayleigh-Ritz method and energy principles. The model allows was implemented in MAPLE18. The results for the nonconservative loading present interesting comparisons illustrating the effect of shear deformation in thickness and thin circular annular plates.
