ALGORITHMS FOR THE RESEARCH OF STRENGTH AND STABILITY OF REINFORCED ORTHOTROPIC SHELLS

Abstract

The paper describes several algorithms based on the method of parameter continuation for thin-walled orthotropic shells. The basis of the study incorporated a mathematical model that takes into account the geometric nonlinearity, lateral shifts, as well as shear and torsional stiffness of the reinforcement. Showing results for several variants of panels conical shells of carbon fiber. A comparison with similar isotropic structures of steel is presented.
