Research into using a fiber Bragg grating sensor group for three-dimensional in situ stress measurement [PDF]
Geoscientific Instrumentation, Methods and Data Systems, 2022 The observation and estimation of the deep crustal stress state is a key and difficult problem for in situ stress measurement. Using a borehole wall strain gauge based on the overcoring stress-relieving method is one of the main methods of in situ stress

STRESS-STRAIN MEASUREMENT IN HEAVY LIQUID METALS
MM Science Journal, 2022 The mechanical testing in heavy liquid metals is performed in order to obtain information about the influence of the liquid metal on Generation IV candidate construction materials. For testing in heavy liquid metal environment, it is required to test comparably with standards of mechanical testing in air at high temperatures.

Capability of Triaxial Apparatus with Respect to Evaluation of Nonlinearity of Soil Stiffness [PDF]
Archives of Civil Engineering, 2020 Reliable evaluation of stress-strain characteristics can be done only in the laboratory where boundary conditions with respect to stress and strain can be controlled. The most popular laboratory equipment is a triaxial apparatus.

Feasibility on accurate measurement of non-uniform strain field through contact methods
Applications in Engineering Science, 2021 When straight material filaments do not remain straight after deformation, the strain varies spatially. These spatially varying strain fields arise because of (1) non-uniform distribution of boundary traction, (2) presence of residual stress in the ...

Correction to : Estimating Measurement Uncertainty on Stress-Strain Curves from SHPB [PDF]
Experimental Mechanics, 2020 Equation (12) in the original article [1] gives the strain from the measured voltage on a full bridge configuration of the four strain gages. The full-bridge is intended to measure tension-compression strain (type III full-bridge), the correct equation is therefore [2]

Accuracy of Measuring Rebar Strain in Concrete Using a Diffractometer for Residual Stress Analysis
Quantum Beam Science, 2023 Neutron diffraction is a noncontact method that can measure the rebar strain inside concrete. In this method, rebar strain and stress are calculated using the diffraction profile of neutrons irradiated during a specific time period.
