Özet:

 

Time-dependent creep behavior of hollow rotating cylinders made from   functionally graded piezoelectric material has been investigated using   Mendelson's method of successive approximation. All the mechanical, thermal,   and piezoelectric properties are modeled as the power-law distribution of   volume fraction. Based on equilibrium, strain displacement, stress-strain,   and electric displacement relations, a differential equation containing   creep strains for displacement is derived. Creep strains are time-,   temperature-, and stress-dependent, and the closed-form solution cannot be   found for this constitutive differential equation. A semianalytical method   in conjunction with the method of successive approximation has therefore   been proposed for this analysis. Similar to the radial stress histories,   electric potentials increase with time, because the latter is induced by the   former during creep deformation of the cylinder, justifying industrial   application of such a material as efficient actuators and sensors.
