Numerical modelling of the poto-poto by coupling of finite elements and boundary elements for acoustic characterization

open access: yesResults in Engineering, 2022
Sustainable development encourages the construction of buildings based from local raw materials because they are ecological, renewable, available, low energy consumption, less costly, low pollution, and therefore without risk to human health.

Generating finite element method in constructing complex-shaped multigrid finite elements [PDF]

open access: yesEPJ 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.

Application of the Double Approximation Method for Constructing Stiffness Matrices of Volumetric Finite Elements

open access: yesAdvanced Engineering Research, 2023
Introduction. When numerically solving problems of elasticity theory in a three-dimensional formulation by the finite element method, finite elements (FE) in the form of parallelepipeds, prisms and tetrahedra are used.

Study of Silver Ions Diffusion into TiO2NT Using Finite Elements Method

open access: yesOrbital: The Electronic Journal of Chemistry, 2019
The purpose of this paper is to study the diffusion of silver ions, Ag+, into TiO2 nanotubes, using Fick’s second law. The mathematical simulations were carried out using the finite element method to solve this partial differential equation.

Finite superelements method for elasticity problems

open access: yesMathematical Modelling and Analysis, 2005
A Fedorenko Finite Superelements Method (FSEM) for 3D linear elasticity problems is considered. We present special weak statement for traces of original problem solution which natural Bubnov‐Galerkin approximation leads to the FSEM.

Stress Analysis Around Tunnels During Construction Stages Using Finite Elements Method [PDF]

open access: yesEngineering and Technology Journal, 2014
In this study, the stresses around a tunnel during construction stages are discussed. For this purpose, the finite element method (FEM) was adopted as an effective approach to analyze the problem using (SIGMA/W) program.
