Аннотация
The reduced elastic constant, the displacement of the neutral line, moments and stresses are determined for a freely supported beam made of the material with the carbon fiber frame, taking into account Hooke’s law, the hypothesis of flat cross-sections, and the equation of equilibrium of forces. The proposed approach was also implemented to calculate the element of the box-section shell, which is the part of the structure of the ramjet engine for high-speed aircraft. Numerical examples are given.
