| Abstract: | This paper presents an analytical solution for the interaction of electric potentials,
electric displacement, elastic deformations, and describes hygrothermal effect responses
in hollow and solid cylinders, subjected to mechanical load and electric potential. Exact
solutions for displacement, stresses and electric potentials in functionally graded
piezoelectric material are determined using the infinitesimal theory. The material properties
coefficients of the present cylinder are assumed to be graded in the radial direction by a
power law distribution. Numerical examples display the significant of influence of material
inhomogeneity. It is interesting to note that selecting a specific value of inhomogeneity
parameter can optimize the piezoelectric hollow and solid cylinders responses, which will
be of particular importance in modern engineering designs. |
