Modelling of behaviour of metals at high strain rates [PDF]

open access: yes, 2006
The aim of the work presented in this thesis was to produce the improvement of the existing simulation tools used for the analysis of materials and structures, which are dynamically loaded and subjected to the different levels of temperatures and strain ...

Damage and strain rate optical characterisation of standard and tufted non crimp fabric carbon composites for Meso-scale impact models [PDF]

open access: yes, 2009
As global warming is a prime concern to the wellbeing of the planet, lighter planes are a requirement to reduce CO2 emissions. Light structures made of carbon epoxy composite materials are of particular interest but are sensitive to impacts such as

A novel methodology for large strain under intermediate strain rate loading

open access: yesPolymer Testing, 2021
Hopkinson bar has already worked to measure mechanical properties of materials under high strain rates, but it fails to conduct intermediate strain rates loading with considerable deformation. Thereby, a methodology is proposed for achieving enough large

Strain y strain rate para dummies

open access: yesRevista Colombiana de Cardiología, 2011
Desarrollos recientes en el campo de la ecocardiografía han permitido a los cardiólogos cuantificar de manera objetiva la función miocárdica regional y global con base en los conceptos de deformación (strain) y velocidad de deformación (strain rate) que ...

Assessment of left ventricular function in horses with aortic regurgitation by 2D speckle tracking

open access: yesBMC Veterinary Research, 2020
Background Aortic regurgitation (AR) may lead to left ventricular (LV) dilatation, cardiac arrhythmias and heart failure. Close follow-up of horses with AR is therefore paramount to detect onset of cardiac decompensation.

Full-field strain measurement and identification of composites moduli at high strain rate with the virtual fields method [PDF]

open access: yes, 2010
The present paper deals with full-field strain measurement on glass/epoxy composite tensile specimens submitted to high strain rate loading through a split Hopkinson pressure bar (SHPB) device and with the identification of their mechanical properties ...

Strain and Strain Rate Echocardiography

open access: yesMethodist DeBakey Cardiovascular Journal, 2006
Myocardial function is eventually determined by the shortening and lengthening of myocardium, i.e., myocardial deformation or strain. The exact and direct measure of myocardial deformation has been dependent on the in vitro analysis of myocardial length.
