The specimen consisted of two materials.
Feasible materials of this part are steel or copper.
For the latter, two cases were considered – a sharp interface between the two materials and a gradually changing one.
Firstly, the interface between materials was a plane.

Abstract: Concrete is one of the most resourceful and environmental friendly building materials.
Compared with other constructive materials it has the less cost/strength ratio.
Fibre reinforced concrete (FRC) may be defined as a composite materials made with Portland cement, aggregate, and incorporating discrete discontinuous fibres.

However, due to a lot of reasons, the gradual expansion and convergence of the micro-defects lead to the macro deterioration of the mechanical properties of materials.
Also, under the action of the loads, the gradual expansion and convergence of the micro-defects lead to the macro deterioration of the mechanical properties of materials.

Introduction The features of rubber materials are low strength, low wave propagation velocity and low mechanical impedance.
These mechanical characteristics of rubber materials provide the damping capacities of severe vibration and shock loadings.
