Název v původním jazyce

Free warping analysis and numerical implementation

Popis výsledku v původním jazyce

This article deals with the mathematical description and numerical implementation of the free warping problem. The solution of the warping problem is given by a warping function obtained by solving the Laplace equation with a corresponding boundary condition. An analytical solution is available only for a limited number of specific cross-sectional shapes such as ellipse or rectangle. For the solution of a general cross section, the Laplace equation must be solved numerically by the finite element method. From a mathematical point of view, the free warping problem can be described in the same way as the heat transfer phenomena, but in the numerical implementation, there are several features specific to warping analysis. The solution algorithm has been implemented in the OOFEM open-source finite element code and verification has been done on several examples with known analytical solutions.
