AbstractConstruction of fringe effect relationships for a cylindrical shell with thickness asymmetrically changing on length is considered. The method asymptotic integration of the differential equations of a three-dimensional problem of the theory of elasticity is applied. By means of special oblique-angled system of coordinates relationships similar to relationships of fringe effect for a cylindrical shell with a constant thickness are received. The basic differential equation of the fourth order with variable factors by to introductions of a new variable is led to a kind which common decision is expressed through modified functions Bessel. The example of calculation of the shell rigidly restrained on one edge is considered. Influence of lengths and thickness of a shell on components of tensely deformed condition analyzed.
