On Two Properties of Shunkov Group
One of the interesting classes of mixed groups ( i.e. groups that can contain both elements of finite order and elements of infinite order) is the class of Shunkov groups. The group $G$ is called Shunkov group if for any finite subgroup $H$ of $G$ in the

MODELLING OF SOIL BEHAVIOR IN DYNAMIC LOAD
The paper focuses on simulation of dynamic “structure – soil” interaction and unbounded soil halfspace. Principles for new finite elements developed in LIRA-SAPR software are described.

In this work, residual stresses arising after an industrial TIG welding process on an aerospace grade part are investigated. The customer demand for high product resistance and high dimensional accuracy calls for the control of the welding process and ...

Adaptive finite element methods
This is a survey of the theory of adaptive finite element methods (AFEMs), which are fundamental to modern computational science and engineering but whose mathematical assessment is a formidable challenge. We present a self-contained and up-to-date discussion of AFEMs for linear second-order elliptic PDEs and dimension d > 1, with emphasis on ...

The tempered finite element method
In this paper, we propose a new approach -- the Tempered Finite Element Method (TFEM) -- that extends the Finite Element Method (FEM) to classes of meshes that include zero-measure or nearly degenerate elements for which standard FEM approaches do not allow convergence.

CENTRIFUGAL FAN IMPELLER FAILURE ANALYSIS USING FINITE ELEMENTS
Este artículo es un análisis de falla ayudado por el modelado matemático de un rodete de un abanico centrífugo que formaba parte del quemador de una caldera de vapor saturado con una capacidad nominal de 1175 kW [120 cv].

Contact analysis using Trefftz and interface finite elements
Hybrid- Trefftz (HT) finite element (FE) analysis of two-dimensional elastic contact problems is addressed with the aid of interface elements and an interfacial constitutive relation. This paper presents the formulation of a four-noded HT finite element

Hierarchic finite elements for thin plates and shells
We consider the numerical approximation of thin plate and shell structures. The plate model is described following the Reissner-Mindlin assumptions while the shell is described using the Naghdi formulation.

The beam finite element with five nodal degrees of freedom
The article presents comparative calculations of reinforced concrete beams using two types of beam finite elements: with three and five nodal degrees of freedom. Calculations were performed both taking into account the concrete and reinforcement physical

ELEMENTS: A high-order finite element library in C++
We discuss the creation and implementation of a generalized library, named ELEMENTS, of mathematical functions for supporting a very broad range of element types including: linear, quadratic, and cubic serendipity elements in 2D and 3D; high-order ...
