| Abstract: | Based on the general solution of the three-dimensional problem for piezoelectric materials, the problem of a piezoelectric
cone subjected to concentrated loads at its apex is solved by trial-and-error method. The displacements and stresses are explicitly
given for the cases of compression in the presence of point charge, bending and torsion. These solutions are simple in form
and convenient for application. When the apex angle 2α equals π, the solutions for concentrated force, point charge and torsion
reduce to solutions of the half-space problem.
