A multi-nodal ring finite element for analysis of pipe deflection
Fonseca, E.M.M.; Melo, F.J.M.Q. de; Madureira, M.L.R.The main objective of this work is to present a numerical formulation to solve the problem of the deformation analysis ot thin-walled circular cylindrical pipes under concentred loads. The solutions is based on a displacement field entirely defined from a set of trigonometic functiobns where the amplitudes are assigned as a nodal paramenters in a multi-nodal finite element. With this formulation it is possible ...
The deformation of cylindrical shells subjected to radial loads
Madureira, M.L.R.; Fonseca, E.M.M.; Melo, F.J.M.Q. deCylindrical shells have a simple geometry and application in pressure vessels and piping engineering. The development of calculation algorithms in structural project is impelled by a constant challenge in the search of more accurate and fast design tools in engineering. The objective of this work is to contribute with a simple and reliable numerical tool for the stress analysis of cylindrical vessels subjected ...
Out of plane bending in curved pipes.
Madureira, M.L.R.; Fonseca, E.M.M.; Melo, F.J.M.Q. dePiping structures have large application in power generation and chemical plants. Given their complexity and construction safety standards, the development of accurate numerical methods has been analyzed by several authors [1,2,3] with trigonometric solutions. Also pipe finite elements, with a considerable amount and complexity of work, has been used to define accurate models for numerical approach of the stres...
The deformation of cylindrical shells subjected to radial loads
Madureira, M.L.R.; Fonseca, E.M.M.; Melo, F.J.M.Q. deThe exact bending solutions of moderately thick rectangular plates with two opposite sides simply into Hamilton cononical equations. Then the whole state variables are separeted. According to the method of eigenfunction expansion in the symplectic geometry, the exact bending solutions of the plates are used and there is no need to select the deformation functions arbitrary, the approach utilized is completely r...
