A higher‐order triangular plate bending element revisited
International Journal for Numerical Methods in Engineering, 1990AbstractA new formulation of an eighteen‐degrees‐of‐freedom higher‐order triangular plate bending element using triangular area co‐ordinates is presented. The displacement function w is taken as the complete fifth‐order polynomial in area co‐ordinates. The normal slope along an edge of the triangle is constrained to vary cubically.

Synthetic circuit elements of higher order with current conveyors
Asia-Pacific Conference on Circuits and Systems, 2003The design of a synthetic element of higher-order immittance function using transformation circuits is described. A new current conveyor structure for low x-terminal input impedance has been used and its model has been presented. PSpice simulation of a third-order Chebyshev lowpass filter is included.

Higher order finite element analysis of lake circulation
Computers & Fluids, 1973Abstract The finite element method is applied to the analysis of the wind-driven circulation of variable-depth, shallow, homogenous lakes. Attention is concentrated upon higher-order description of the flow phenomena within the individual elements and upon the use of these higher order functions in the definition of curved element boundaries ...

Accurate surface embedding for higher order finite elements
Proceedings of the 12th ACM SIGGRAPH/Eurographics Symposium on Computer Animation, 2013In this paper we present a novel approach to efficiently simulate the deformation of highly detailed meshes using higher order finite elements (FE). An efficient algorithm based on non-linear optimization is proposed in order to find the closest point in the curved computational FE mesh for each surface vertex.

Two-Dimensional Higher Order Elements
2014The triangular elements with quadratic and cubic shape functions in terms of the local area coordinates are presented and coordinate transformation law with the associated Jacobian matrix calculations are given in the chapter. As an application, the Field problem in two dimensions is considered and employing the quadratic triangular element, the ...

Union-Preserving Transformations of Higher Order Surface-Elements
American Journal of Mathematics, 19471. Curve-element transformations of the union-preserving type. In 1943, Kasner and De Cicco began the study of transformations in the plaie and in space from differential elements of order n into those of first order.' We have termed such a correspondence union-preserving if it converts every union into a union.
