In a normal heart, the longitudinal strain is negative as measured from end-diastole.

It has been shown clinically that longitudinal strain rate and wall thickening are diagnostically equivalent.

Stress in the rail due to temperature variations is absorbed without longitudinal strain, except near bridges where an expansion joint is sometimes used.

The strain pulse forms a pancake-like region of longitudinal strain that propagates directly into the solid away from the surface.

Longitudinal Strain (Ell)

The longitudinal strains, predicted by a nonlinear flexural analysis accounting for shrinkage and construction stages, compare well with the strains measured during the test.

The fiber strain (εf) experienced by the longitudinal red muscle fibers is equivalent to the longitudinal strain (εx).

The liquid is therefore in tension and sustains a longitudinal strain which, in the absence of disturbing factors, is insufficient to break the column of liquid"."

The method is limited to one direction; along the ultrasound beam, can thus mainly be used from the apical window, and for longitudinal strain and strain rate measurements only.

In the study by Cho et al, both TVI derived and speckle tracking derived longitudinal strain showed modest correlation with MRI derived strain.

Architectural gear ratio, also called anatomical gear ratio, (AGR) is a feature of pennate muscle defined by the ratio between the longitudinal strain of the muscle and muscle fiber strain.

The linear portion of the curve is the elastic region and the slope is the modulus of elasticity or Young's Modulus ( Young's Modulus is the ratio of the compressive stress to the longitudinal strain).

Since a length of pipe undergoing vibration experiences alternate tensile and compressive forces as waves along its longitudinal axis (and therefore longitudinal strains), its diameter will expand and contract in unison with the applied tensile and compressive waves.

For instance, Gregory T. Armstrong, M.D., of St. Jude Children's Research Hospital, and his colleagues recently found that assessing cardiac health using echocardiographic measures known as global longitudinal strain and diastolic function may help identify cancer survivors who are at high risk of treatment-induced cardiac disease.
