Improved Thin-Walled Finite Curved Beam Elements

open access: yesAdvances in Mechanical Engineering, 2013
The two- and three-noded spatially coupled thin-walled finite curved beam elements are presented on the basis of assumed strain fields. These elements consider the extensional/inextensional conditions along the centroid axis of curved beam.

Direct determination of shape functions for isoparametric elements with arbitrary node configuration

open access: yesOpen Engineering, 2015
Shape functions have been derived to describe different forms of elements, notably triangles and rectangles in 2-D, and tetrahedrons, cuboids, and triangular prisms in 3-D.

Modelling drawbeads with finite elements and verification [PDF]

open access: yes, 1994
Drawbeads are commonly used in deep drawing processes to control the flow of the blank during the forming operation. In finite element simulations of deep drawing the drawbead geometries are seldom included because of the small radii; because of these ...

Polynomial representation of hybrid finite elements

open access: yesComputer Assisted Methods in Engineering and Science, 2023
We introduce the hybrid-Trefftz FE formulations for linear statics of solids as well as for linear (slow velocity) steady fluid dynamics. Moving least square procedure is given to obtain continuous secondary fields (such as stresses for solids), which ...

Solution representations for Trefftz-type finite elements

open access: yesComputer Assisted Methods in Engineering and Science, 2023
Solution representations are available for several differential equations. For elasticity problems some of the solution representations are considered in this paper.

Finite Dynamic Elements and Modal Analysis

open access: yesShock and Vibration, 1993
A general modal analysis scheme is derived for forced response that makes use of high accuracy modes computed by the dynamic element method. The new procedure differs from the usual modal analysis in that the modes are obtained from a power series ...

Resolving Boundary Layers with Harmonic Extension Finite Elements

open access: yesMathematical and Computational Applications, 2022
In recent years, the standard numerical methods for partial differential equations have been extended with variants that address the issue of domain discretisation in complicated domains.

Finite elements mathematical model of geometric nonlinearity

open access: yesTrudy 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

Finite groups with 4p2q elements of maximal order

open access: yesOpen Mathematics, 2021
It is an interesting and difficult topic to determine the structure of a finite group by the number of elements of maximal order. This topic is related to Thompson’s conjecture, that is, if two finite groups have the same order type and one of them is ...
