Magnetoelastic thin films at large strains. [PDF]

open access: yesContin Mech Thermodyn, 2021
AbstractStarting from the three-dimensional setting, we derive a limit model of a thin magnetoelastic film by means of $$\varGamma $$ Γ -convergence techniques. As magnetization vectors are defined on the elastically deformed configuration, our model features both Lagrangian and Eulerian terms.

Finite element analysis of hyperelastic shells without any local iterative calculations by block Newton method

open access: yesNihon Kikai Gakkai ronbunshu, 2022
The simultaneously iterative procedure proposed by the authors is extended to hyperelastic shells. The weak form of the equilibrium equation and the plane stress condition at every material point are defined as a coupled problem, and a numerical ...

Experiments and numerical simulations of Lueders bands and Portevin–Le Chatelier effect in aluminium alloy AW5083

open access: yesArchives of Mechanics, 2023
This work is focused on the modelling of experimental behaviour of a bone-shape sample made of aluminium alloy AW5083 under tension. This behaviour involves propagating instabilities, namely Lueders bands and the Portevin–Le Chatelier effect. A series of

Flow modelling of Ti6Al4V under large strains [PDF]

open access: yesMATEC Web of Conferences, 2020
This work uses flow stresses obtained experimentally at different strain rates and temperatures to validate flow modelling results. Flow curves of Ti6Al4V are measured via torsion experiments with a Gleeble® 3800 up to effective strains of 8.

FINITE ELEMENT IMPLEMENTATION OF GEOMETRICALLY NONLINEAR CONTACT

open access: yesActa Polytechnica CTU Proceedings, 2021
The OOFEM finite element software has been recently updated to include contact algorithms for small strain applications. In this work, we attempt to extend the contact algorithms to large strain problems.

On Spatial vs Referential Isotropic Fourier’s Law in Finite Deformation Thermomechanics

open access: yesEngineering Transactions, 2023
This paper deals with the issue of isotropic heat conduction in thermomechanical largestrain problems. The aim of the paper is a comparison of different variants of Fourier’s law used in the literature for a large strain problem.

Large strain creep analysis of composite thick-walled anisotropic cylinders

open access: yesJournal of Mechanical Engineering and Sciences, 2023
Creep analysis of a thick-walled composite anisotropic cylinder under internal pressure and considering large strains is presented. Using a threshold creep law for composite materials, expressions for stresses, strains, and strain rates are derived for ...

Combined blast and vibratory machines effect on in-service structures

open access: yesAlexandria Engineering Journal, 2023
Large cement storage towers are commonly exposed to both quarry production blasting and the excitations from vibratory plant. Several seismographs were placed in the quarry to monitor blast-induced vibrations in the vicinity of the cement plant. Moreover,

Strain Hardening at Large Strains [PDF]

open access: yes, 1989
The strain hardening properties of various fcc metals have been investigated at large strains by means of torsion tests of short thin-walled cylinders. The results show that Stage IV occurs in all cases provided that a low enough test temperature is used; it is a nearly constant hardening rate of 2.10/sup /minus/4/ G in terms of resolved flow stress ...
