Strain rate dependency of dislocation plasticity
Nature Communications, 2021 The relationship between the strain rate and micro-scale deformation in metals is still poorly understood. Here the authors use discrete dislocation dynamics and molecular dynamics to establish a universal relationship between material strength ...

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

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.

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.

Timing and rate of global contraction on Mercury
Geophysical Research Letters, 2017 Impact bombardment and global contraction due to planetary cooling have both shaped the surface of Mercury over very long time scales. Landforms associated with these processes, i.e., impact craters and thrust fault‐related escarpments, and their mutual ...

Experimental study on effect of graded loading rate on creep characteristics of anthracite
Meikuang Anquan, 2022 In order to study the effect of graded loading rate on creep characteristics of anthracite, the effects of graded loading rate and stress level on instantaneous strain, creep strain and creep rate of coal samples were analyzed by triaxial creep tests of

Effect of strain rate on serrated load of indentation in Al-Mg alloy
Nihon Kikai Gakkai ronbunshu, 2017 Indentation tests are used to determine the local mechanical properties of materials. Previously, the indentation strain rate was correlated with the strain rate in uniaxial tests based on the hardness, which was the obtained load divided by the cross ...
