Strain Measurement

Measurement, Instrumentation, and Sensors Handbook, 2018
Fiber Bragg grating(FBG) sensors, one of the fiber optic sensors(FOS), based on the wavelength division multiplexing(WDM) technology are ideally suitable for structural health monitoring of composite materials and structures.

A mechanical model to interpret distributed fiber optic strain measurement at displacement discontinuities

Structural Health Monitoring, 2020
Distributed fiber optic (strain) sensing, which provides the unique advantage of sensing damage (e.g. cracking) at locations that are not known a priori, has been increasingly used in civil engineering.

Clinical Utility of Echocardiographic Strain and Strain Rate Measurements

Current Cardiology Reports, 2021
Assessment of left ventricular function is pivotal in many decisions, but ejection fraction has fundamental limitations for assessment of mild dysfunction, and especially for repeated assessments. Myocardial deformation imaging using speckle-tracking is widely available on modern echocardiography systems, and is now feasible as a clinical, rather than ...

Strain measurement during tensile testing using deep learning-based digital image correlation

Measurement science and technology, 2019
This paper describes a novel non-contact strain measurement method defined as deep learning based on digital image correlation (DDIC). In particular, it is very difficult to measure directly displacement of gauge length during tensile testing of thin ...
