Analysis of Stress Concentration with a Controlled Error in Thin-Walled Structures (Transport and Launch Container)

Autor: Yu. I. Vinogradov

Publikováno v: Mechanics of Solids. 56:230-241

The choice of a transport and launch container (TLC) for analyzing the stress concentration in its elements does not reduce the generality of the proposed methodology for solving problems for other thin-walled structures. The TLC is, as a rule, a cyl

Study of Stress-Strain State of an Aircraft Body at Steering Loads

Autor: G. B. Menkov, Yu. I. Vinogradov

Publikováno v: Mechanics of Solids. 55:423-436

A design scheme is considered: a cylindrical shell, which is loaded concentrated through the frame. A classical mathematical model is used for the adopted calculation scheme. Based on the mathematical model, the initial problem is analytically solved

Autor: Yu. I. Vinogradov, M. V. Konstantinov, A. V. Belyaev

Publikováno v: Mechanics of Solids. 53:329-339

Aerospace and other systems usually have spherical tanks, as the most optimal in terms of weight ratio. The functional units of such systems are connected by frames. Consequently, tanks (spherical shells) are loaded locally in them. In this case, the

Publikováno v: Russian Aeronautics. 61:156-164

The equations of the mathematical model are solved in terms of special functions. The results for the design scheme of the aircraft forebody are obtained with a guaranteed accuracy by the stable method of functional normalization.

Scope of inextensible frame hypothesis in local action analysis of spherical reservoirs

Autor: Yu. I. Vinogradov

Publikováno v: Mechanics of Solids. 52:342-352

Spherical reservoirs, as objects perfect with respect to their weight, are used in spacecrafts, where thin-walled elements are joined by frames into multifunction structures. The junctions are local, which results in origination of stress concentrati

Analytical and asymptotic solution of boundary value problems in the mechanics of deformed shells under concentrated loading

Autor: Yu. I. Vinogradov, V. N. Bakulin

Publikováno v: Russian Aeronautics. 60:13-20

The paper proposes an analytical interval conjugation method for solving boundary value problems in the mechanics of deformed shells under concentrated loading. The errors are evaluated in solving the similar problems by means of asymptotic formulas.
