Coeficientes de Pandeo para Placas Anulares con Espesor Variable

Patricia M. Ciancio


In this work, an approximate solution is presented to find the coefficient of elastic buckling, used in the determination of critical loads, for thin annular plates of variable thickness, and with its clamped external edge. Being the topic of interest in aerospace, civil, naval engineering, among others.
The proposal consists on applying the method of Rayleigh Ritz optimized , to calculate the coefficient of buckling a function of other parameters, in way of minimizing the factor of buckling for the determination of critical loads.
The obtained results were contrasted with values that appear in the literature, and they showed an appropriate approach.
