Effect of Change in the Curvature Parameters on the Stress State of Concave Corrugated Hollow Cylinders

The effect of change in the curvature parameters of the stress state of concave corrugated hollow cylinders is studied. The change is attributed to variations in the radius of a moving circle and in the distance to its center. The problem is solved in spatial statement using analytical methods of separation of variables, approximation of functions by discrete Fourier series, and the numerical discrete-orthogonalization method. Results are presented in the form of plots demonstrating distributions of displacement and stress fields and are analyzed.
