Finite element differential forms on cubical meshes [PDF]
, 2013 We develop a family of finite element spaces of differential forms defined on cubical meshes in any number of dimensions. The family contains elements of all polynomial degrees and all form degrees. In two dimensions, these include the serendipity finite

Cancellative Elements in Finite AG-groupoids
Journal of New Theory, 2020 An Abel-Grassmann's groupoid (briey AG-groupoid) is a groupoid Ssatisfying the left invertive law: (xy)z = (zy)x for all x, y, z \in S. In the present paper, wediscuss the left and right cancellative property of elements of the nite AG-groupoidS.

International Journal for Computational Civil and Structural Engineering, 2020 The article describes new types of finite elements that allow you to take into account all six degrees of freedom of the shell. In order to compose the finite elements, the Allman functional with a rotational degree of freedom is used.

The Hellan-Herrmann-Johnson Method for Nonlinear Shells
, 2019 In this paper we derive a new finite element method for nonlinear shells. The Hellan-Herrmann-Johnson (HHJ) method is a mixed finite element method for fourth order Kirchhoff plates.

Aluminum Extrusion Simulation Using Finite Elements
EngThe complexity of an extrusion die profile is determined by its geometry. Various metrics such as the complexity index, shape factor, and form factor are used to quantify how geometric intricacy affects production costs, die life, energy consumption ...

Quantum Finite Elements for Lattice Field Theory
, 2016 Viable non-perturbative methods for lattice quantum field theories on curved manifolds are difficult. By adapting features from the traditional finite element methods (FEM) and Regge Calculus, a new simplicial lattice Quantum Finite Element (QFE ...
