Strain y strain rate para dummies
Revista 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 ...

Strain and strain rate: An emerging technology in the perioperative period
Annals of Cardiac Anaesthesia, 2016 Newer noninvasive parameters are being used for perioperative detection of myocardial ischaemia. TDI and global strain rate are some of these parameters. TDI signal is a modification of the routine Doppler flow signal.

Non-Newtonian Rheology of Igneous Melts at High Stresses and Strain Rates: Experimental Results for Rhyolite, Andesite, Basalt, and Nephelinite [PDF]
, 1990 The stress-strain rate relationships of four silicate melt compositions (high-silica rhyolite, andesite, tholeiitic basalt, and nephelinite) have been studied using the fiber elongation method.

Stress-strain synchronization for high strain rate tests on brittle composites [PDF]
, 2018 Nowadays, many researchers develop rate-dependent composite material models for application in dynamic simulations. Ideally, full stress-strain curves at a wide range of strain rates are available for identification of the different parameters of these ...

Strain Rate Induced Crystallization in Bulk Metallic Glass-Forming Liquid [PDF]
, 2006 We report on the solidification of Au49Ag5.5Pd2.3Cu26.9Si16.3 bulk metallic glass under various strain rates. Using a copper mold casting technique with a low strain rate during solidification, this alloy is capable of forming glassy rods of at least 5 ...

Myocardial strain and strain rate in Kawasaki disease [PDF]
European Heart Journal - Cardiovascular Imaging, 2013 We sought to determine whether velocity vector imaging (VVI)-derived left ventricular (LV) myocardial deformation indices could detect subtle myocardial abnormalities in acute Kawasaki disease (KD).The study cohort of children with KD was divided by coronary artery dilation (CAD, Z-score >2.5) and/or uncomplicated vs.

Strain and Strain Rate Echocardiography
Methodist 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.

Effect of changing strain rate on flow stress during hot deformation of type 316L stainless steel [PDF]
, 2008 ompression testing has been used with ramped changes in strain rate during deformation, and with changes in strain rate between double deformations to study their effects on flow stress.
