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

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

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

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

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.
