An Extensometer for Circumferential Strains
Journal of Testing and Evaluation, 1975Abstract An instrument is described for measuring circumferential strains in plastic specimens of circular cross section. It consists of four direct-current differential transformers (DCDTs) suitably mounted on an invar ring. The DCDTs probe the position of the surface of the specimen at opposite ends of two mutually perpendicular ...

The oesophagus is subjected to large axial strains in vivo and the zero-stress state is not a closed cylinder but an open circular cylindrical sector. The closed cylinder with no external loads applied is called the no-load state and residual strain is the difference in strain between the no-load state and zero-stress state.

Circumferential and Axial Strain in the Proximal Femur
Clinical Orthopaedics and Related Research, 1980Because the Charnley-Müller prosthesis inserted in a varus position has been found subject to loosening, circumferential and longitudinal strain patterns were determined in proximal cadaver femora that had been instrumented with strain gauge rosettes and implanted with total hip replacement femoral prostheses.

Longitudinal and Circumferential Strain in Patients with Regional LV Dysfunction
Current Cardiology Reports, 2013The multilayer, helical arrangement of myofibers within the left ventricular myocardium forms the fundamental basis of the complex, multidimensional deformation of the left ventricle during the cardiac cycle. Echocardiographic characterization of the different components of this dynamic process not only provides a means to quantify the myocardial ...

Circumferential strains of a concrete specimen in a pullout test
Structural Concrete, 2019Pullout test of a rebar from an axisymmetric concrete specimen yields the bond‐slip relationship characterizing the rebar‐concrete interfacial constitutive relationship. It is assumed that inclined compressive forces are developed between the rebar ribs and the concrete during pullout. The components of the inclined forces that are perpendicular to the

Comparison of SPAMM and SENC Methods for Evaluating Peak Circumferential Strain at 3T
Magnetic Resonance in Medical Sciences, 2013 We compared peak circumferential strain (Ecc) values with spatial modulation of magnetization (SPAMM) and strain-encoded (SENC) magnetic resonance (MR) imaging at 3 tesla. Correlation coefficients of the averaged peak Ecc values of the 2 methods were statistically significant.

Circumferentially sinusoidal stress and strain in shells of revolution
International Journal of Solids and Structures, 1970Abstract The system of equations of the linear theory of isotropic elastic shells of revolution for stress and strain sinusoidal in the polar angle of the base plane with period 2 π is reduced to two simultaneous second order ordinary differential equations which are remarkably similar to the corresponding equations for symmetric bending.

Abnormal Circumferential Strain is Present in Young Duchenne Muscular Dystrophy Patients
Pediatric Cardiology, 2013Advances in management of non-cardiac issues in Duchenne muscular dystrophy (DMD) have improved such that DMD-associated cardiac disease has become the leading cause of death for such patients. Cardiac dysfunction measured by standard transthoracic echocardiographic methods, e.g., fractional shortening (FS) and ejection fraction (EF), is rarely present

ABSTRACTA Barlow‐type electromechanical strain gauge and an indium/gallium‐in‐rubber strain gauge were compared for linearity of output, replicability, stability, and sensitivity to temperature changes. Distension of the strain gauges was achieved by placing them on standard size glass dilators, while temperature changes were produced and monitored in ...

Dispersion of circumferential waves in cylindrically anisotropic layered pipes in plane strain
The Journal of the Acoustical Society of America, 2008Dispersion spectra of circumferential waves along the periphery of circular pipes made of layered anisotropic materials do not seem to be available in literature. This note attempts to partially fill this gap by providing the dispersion spectra in two and three layered cylindrically anisotropic pipes in plane strain motion.
