Abstract :
An analytical-numerical method is offered to study the stationary wave fields in unbounded elastic medium, scattered by elastic fibre with interfacial layer of variable thickness and low stiffness. An elastic system is under conditions of longitudinal shear. An algorithm of study is based on the modified null-field method. The influence of mechanical and geometric parameters of composite on the amplitude-frequency characteristics of SH-waves scattered by a fibre of noncanonical shape into a far zone is analyzed.
