摘要：

We present an analytical solution to the boundary-value problem in the classical theory of elasticity for a core-shell nanowire with a core in the form of a long parallelepiped with a square cross section. The core is placed symmetrically with respect to the cylindrical shell surface. The misfit stresses are found in a concise and transparent form of trigonometric series, which is convenient for practical use in theoretical modeling of misfit relaxation mechanisms. This work was supported by Peter the Great St. Petersburg Polytechnic University and ITMO University.
