Forced oscillations of the elastic strip with a longitudinal crack

Abstract

© 2015 Kristina Stekhina and Dmitrii Tumakov. The problem of forced oscillations of an elastic strip containing a longitudinal crack of a finite length is considered. The diffraction problem is reduced to the system of paired integral equations. The system of integral equations is reduced to the system of linear algebraic equations by using the Galerkin method. Singularities of integrand functions, through which coeffcients of the system matrix are calculated, are determined.
