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.

Rheology and ultrasonic properties of Pt57.5Ni5.3Cu14.7P22.5 liquid [PDF]
, 2007 The equilibrium and nonequilibrium viscosity and isoconfigurational shear modulus of Pt57.5Ni5.3Cu14.7P22.5 supercooled liquid are evaluated using continuous–strain-rate compression experiments and ultrasonic measurements. By means of a thermodynamically-

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

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 ...

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 ...

Stress transfer and strain rate variations during the seismic cycle [PDF]
, 2004 The balance of forces implies stress transfers during the seismic cycle between the elastobrittle upper crust and the viscoelastic lower crust. This could induce observable time variations of crustal straining in the interseismic period.
