Abstract
A theoretical study on the effective magnetoelectroelastic (MEE) properties of the multi-coated nanocomposites is reported based on a generalized self-consistent model with surface MEE effect under far-field antiplane shear load, inplane electric load and inplane magnetic load. A rigorous analytical solution of overall generalized MEE stress and strain fields in each component is presented via the complex potential function theory. The closed-form solution of the effective MEE coefficients is obtained by using the average-field theory. Several existing and new results can be regarded as the special cases of the present solution. A comparison with other theoretical results shows good agreement, which illustrates the accuracy of the proposed method. Numerical examples reveal the size dependence of the effective MEE coefficients when the size of the coated fiber is at nanoscale. Several typical MEE composites with the epoxy matrix are investigated, and the influences of the microstructure parameters on the magnetoelectric coupling effect are discussed.
