Circumferential Shear Strain in Torsion-Based Severe Plastic Deformation

Scripta Materialia, 2014
The dependence of the circumferential shear strains of two different shear modes in a cylindrical coordinate system on the shear planes during a torsion-based severe plastic deformation is investigated using strain–displacement relationships. Contrasting trends in the circumferential shear strains (increasing ezθ and decreasing erθ with radial distance

Circumferential and Longitudinal Ventricular Strain in the Normal Human Fetus [PDF]

Journal of the American Society of Echocardiography, 2012
Echocardiography with speckle tracking is a novel, angle-independent technique for assessing global and regional cardiac function. Normal data on longitudinal strain have been reported for human fetuses. The aim of this study was to define circumferential left ventricular (LV) strain in a normal fetal population.Singleton fetuses between 17 and 42 ...

Link between myocardial deformation phenotyping using longitudinal and circumferential strain and risk of incident heart failure and cardiovascular death.

European Heart Journal-Cardiovascular Imaging, 2023
AIMS Left ventricular (LV) systolic deformation is altered early in the ventricular disease process despite normal LV ejection fraction (LVEF). These alterations seem to be characterized by decreased global longitudinal strain (GLS) and augmented global ...

Age- and sex-based normal values of layer-specific longitudinal and circumferential strain by speckle tracking echocardiography: the Copenhagen City Heart Study.

European Heart Journal-Cardiovascular Imaging, 2021
AIMS Technical advancements in 2D-speckle tracking echocardiography (2DSTE) have allowed for quantification of layer-specific global longitudinal strain (GLS) and circumferential strain (GCS) of the left ventricle (LV).

Age-, Sex- and Race-based Normal Values for Left Ventricular Circumferential Strain from the World Alliance of Societies of Echocardiography Study.

Journal of the American Society of Echocardiography, 2022
BACKGROUND Left ventricular (LV) circumferential strain has received less attention than longitudinal deformation, which has recently become part of routine clinical practice. Among other reasons, this is because of the lack of established normal values.
