Thermoviscoelastic equilibrium of multilayer orthotropic shells of revolution

Subject of inquiry: laminated shell-type constructions made from thermorheologically simple and composite materials. The aim of the work is to develop a numerical technique for the investigation of thermoviscoelastic equilibrium of laminated orthotropic shells of revolution made of thermorheologically composite materials under simultaneous action of temperature pattern and fields of forces. Differential equations for quasi-static equilibrium of laminated shells of revolution have been obtained; a procedure for numerical solution of boundary-value problems of statics of multilayer shells made from thermorheologically composite materials has been developed; quality and degree of influence of geometrical and physico-mechanical characteristics has been ascertained. A method and an algorithm has been developed which is realized in the application program package for ES-type, SM-type and PC computers. Particular applied problems have been solved for the designing of a five-layer truncated spherical shell and a three-layer cylindrical shell proper gravity action, temperature and snow load. The results of the investigations have been used at the Mechanics Institute of the Ukrainean Academy of Sciences when designing these constructions. The obtained new results allow to realize a more well-founded approach when designing stress-strained conditions of multilayer shells of revolution made of temperature sensitive and viscoelastic materialsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
