Finite elements mathematical model of geometric nonlinearity
Trudy Odesskogo Politehničeskogo Universiteta, 2015 The article considers the construction of a mathematical model for accounting the geometric nonlinearity at finite elements method. The built model takes into account the changes in system stiffness matrix when changing its shape. In quality of an object

Generating finite element method in constructing complex-shaped multigrid finite elements [PDF]
EPJ Web of Conferences, 2019 The calculations of three-dimensional composite bodies based on the finite element method with allowance for their structure and complex shape come down to constructing high-dimension discrete models.

Hanging nodes for higher-order Lagrange finite elements
Examples and Counterexamples, 2021 We report in this work an extension of hanging nodes theory for Lagrange elements to higher-order elements. Concrete values of the constants that appear in the applications are also provided.

Finite element formulations for 3D convex polyhedra in nonlinear continuum mechanics
Computer Assisted Methods in Engineering and Science, 2017 In this paper, we present finite element formulations for general three-dimensional convex polyhedra for use in a common finite element framework that are well suited, e.g., for modeling complex granular materials and for mesh refinements.

On the Equivalence of Finite Element and Finite Integration Formulations [PDF]
IEEE Transactions on Magnetics, 2010 The paper offers a comparative study of numerical methods of analysis of electromagnetic fields. The focus is on the finite element method (FEM) and finite integration technique (FIT), but with the cell and equivalent network approaches also considered.

Stochastic finite elements: Where is the physics? [PDF]
Theoretical and Applied Mechanics, 2011 The micromechanics based on the Hill-Mandel condition indicates that the majority of stochastic finite element methods hinge on random field (RF) models of material properties (such as Hooke’s law) having no physical content, or even at odds with ...

The Serendipity Family of Finite Elements [PDF]
Foundations of Computational Mathematics, 2011 We give a new, simple, dimension-independent definition of the serendipity finite element family. The shape functions are the span of all monomials which are linear in at least s-r of the variables where s is the degree of the monomial or, equivalently, whose superlinear degree (total degree with respect to variables entering at least quadratically) is

Real Elements and p-Nilpotence of Finite Groups [PDF]
Advances in Group Theory and Applications, 2016 Our first main result proves that every element of order 4 of a Sylow 2-subgroup S of a minimal non-2-nilpotent group G, is a real element of S. This allows to give a character-free proof of a theorem due to Isaacs and Navarro (see [9, Theorem B]). As an
