Solution of Periodic Boundary-Value Problems of the Spatial Theory of Elasticity in the Vector Form

Abstract

© 2019, Springer Science+Business Media, LLC, part of Springer Nature. We discuss boundary-value problems for the system of equations of the spatial theory of elasticity in the class of double-periodic functions and obtain a general solution of the system. We distinguish six types of elementary Floquet waves and examine their energy characteristics. We consider fundamental boundary-value problems in the half-space in the vector form. The diffraction problem for an elastic wave on a periodic system of defects in the vector form is reduced to the paired summator functional equation.
