Three Dimensional Finite Element

As one of the key structures of hydropower underground projects, buried high-pressure steel bifurcations have complex structures and undefined force states. Based on practical condition of the buried high-pressure steel bifurcation of Sandaowan Hydropower Station, a nonlinear three-dimensional finite element model with parametric design language is established to analyze the changing law of the stress of the lining affected by the dimension of the strengthened beams. It is proposed that to increase the height of the strengthened beams can be reduce the phenomenon of stress concentration effectively in the bifurcation, which can be served as a theory reference for the engineering design and construction.

This article deals with the static and dynamic stabilities of cantilever symmetric laminated beams. In this study, three-dimensional finite element model based on the classical lamination plate theory is used. A computer code is developed using MATLAB software to perform the finite element analyses. Effects of the ply orientation, static and dynamic load parameters on the stability are examined. It is observed that ply orientations affect the location and the width of the instability regions.

An existing robust three dimensional finite element based on the strain approach is presented. This element is implemented, for the first time in the commercial computer code ABAQUS, by using the subroutine (UEL), for the static and dynamic analysis of isotropic plates, whatever thin or thick. It is Baptised SBH8 (Strain Based Hexahedral with 8 nodes) and has the advantage to overcome the problems involved in numerical locking, when the thickness of the plate tends towards the smallest values. The implementation is justified by the capacities broader than offers this code, especially, in the free frequencies computation. The results obtained by the present element are better than those given by elements used by ABAQUS code and the other elements found in the literature, having the same number of nodes.

Abstract The effects of variations in stiffness and geometry on the nonuniformity of tires are investigated by using the finite element analysis. In order to evaluate tire uniformity, a three-dimensional finite element model of the tire with imperfections is developed. This paper considers how imperfections, such as variations in stiffness or geometry and run-out, contribute to detrimental effects on tire nonuniformity. It is found that the radial force variation of a tire with imperfections depends strongly on the geometrical variations of the tire.
