Strain and strain rate measurement during the bulge test by electronic speckle pattern interferometry
(ELSEVIER SCIENCE SA, 2007)
This paper presents a new experimental method to measure the strain increment and the strain rate during the bulge of a copper sheet. The electronic speckle pattern interferometry (ESPI) is combined with the bulge test to ...
Analysis of plastic strain localization by a combination of the speckle interferometry with the bulge test
(ELSEVIER SCI LTD, 2007)
The process of localization of strains, diffuse and localized necking, up to fracture in equi-biaxial loading was analyzed through the images obtained by electronic speckle pattern interferometry (ESPI). The problem of ...
Strain localization, strong discontinuities and material fracture: Matches and mismatches
(Elsevier Science Sa, 2012-10)
The work focuses on the connections of strain localization modeling of material failure and discrete fracture mechanics. It is an attempt to give an answer to the old question of whether the finite element solutions of ...
Macroscopic Stress-Strain Response and Strain-Localization Behavior of Biopolymer-Treated Soil
(2022-03-01)
The enhancement of soil engineering properties with biopolymers has been shown recently as a viable and environmentally benign alternative to cement and chemical stabilization. Interest in biopolymer-treated soil is evident ...
Study of a stabilized mixed finite element with emphasis on its numerical performance for strain localization problems
(John Wiley & Sons Ltd, 2008-12)
The numerical performance of a stabilized mixed finite-element formulation based on the pressuregradient- projection method (PGP) using equal-order (linear) interpolation is evaluated by solving solid mechanics problems, ...
Strain distribution due to surface domains: A self-consistent approach with respect to surface elasticity
(Beilstein-Institut Zur Forderung der Chemischen Wissenschaften, 2015-01)
Elastically mediated interactions between surface domains are classically described in terms of point forces. Such point forces lead to local strain divergences that are usually avoided by introducing a poorly defined ...
Partição de deformação em aços dual-phase
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA METALÚRGICAPrograma de Pós-Graduação em Engenharia Metalúrgica, Materiais e de MinasUFMG, 2022-09-29)
The tailoring of new alloys often requires improvement in strength, for performance, and ductility to support mechanical processing until the final shape is achieved. Important advances have been obtained in the last decades ...
On the strong discontinuity approach in finite deformation settings
(John Wiley & Sons Ltd, 2003-05)
Taking the strong discontinuity approach as a framework for modelling displacement discontinuities and strain localization phenomena, this work extends previous results in innitesimal strain settings to finite deformation ...
Variational modelling of strain localization in solids: a computational mechanics point of view
(2020)
Strain localization is one of the most challenging phenomena in solid mechanics. It occurs when strains concentrate in very narrow bands within a solid, typically referred to as localization bands. This behaviour is related ...
The influence of the strain of Trypanosoma cruzi in placental infections in mice
(Transactions of the Royal Society of Tropical Medicine and Hygiene, 1982)
Pregnant female mice were infected with Trypanosoma
cruzi strains which differed according to several
parameters and were classified as three different
types. Mice were killed during either the acute or the
chronic phase ...
