Abstract

The majority of structures in modern technology, industry and production are subjected to the influence of loads. Nowa­days, a wide use of polymers and composite materials requires the study of long preservation of hardness and a problem of de­struction of the structures made of such materials and subjected to the influence of loads.

Using a characteristic method, the destruction of a struc­tural inhomogeneous bar, which is subjected to an impact in its left end in the direction of its axis, was studied, and the depen­dences of the first and full moments of destruction after various mechanical characteristics were found by a numerical compu­tation. Finding of an analytical solution, characterizing the study, is rather difficult and, therefore, the problem was solved approximately. The results show that the effect of proportions of mechanical characteristics of the bar parts on the destruction process is significant.
