EMI-ANALYTICAL ANALYSIS OF A LONG SHALLOW OBLIQUE HELICOIDAL SHELL IN A NON-ORTHOGONAL NON-CONJUGATE COORDINATE SYSTEM

Cover Page

Abstract


The article discusses the problems of analysis of thin shallow shell in the form of oblique helicoid by different methods, particularly, by a semi-analytical method of numerical solution of three equilibrium equations in displacements and by V.G.Rekatch's analytical method, which was not numerically applied in any literature. New variant of analysis of stress-strain state of oblique helicoid shells was developed by applying V.Z. Vlasov's shallow shell the- ory. The equilibrium equations were obtained for three unknown displacements and after the numerical solution was used
