У даній роботі, із використанням просторової моделі лінійної теорії пружності на основі методу апроксимації функцій дискретними рядами Фур’є, суть якого викладена в роботах [1, 11], розв’язано задачу про напружений стан нетонких циліндричних оболонок з гофрованим поперечним перерізом, виготовлених з неперервно-неоднорідного матеріалу, при дії внутрішнього тиску за певних граничних умов на торцях. Для класу розглядуваних оболонок встановлено залежність характеристик напруженого стану від амплітуди гофрування та товщини для трьох законів зміни модуля пружності вздовж товщини.
In this work, using the spatial model of the linear theory of elasticity based on the method of approximation of functions by discrete Fourier series, the essence of which is given in the works [1, 11], the problem of the stress state of non-thin cylindrical shells with a corrugated cross section is solved, made of continuous non-homogeneous material, under the action of internal pressure under certain boundary conditions at the ends. For the class of shells under consideration, the dependences of the stress state characteristics on the corrugation amplitude and thickness was established for three laws of change of the modulus of elasticity along the thickness.
