Direct measurement of strain-dependent solid surface stress [PDF]
Nature Communications, 2017 Solid surface stress is a fundamental property of solid interfaces. Here authors measure the solid surface stress of a gel, and show its dependence on surface strain through a surface modulus.

Estimating Measurement Uncertainty on Stress-Strain Curves from SHPB [PDF]
Experimental Mechanics, 2017 Split Hopkinson Pressure Bar tests are commonly used to determine material stress-strain relationship at high deformation rates. Obtaining this relationship is dependant both on certain assumptions and substantial post-processing of the data recorded during the test. Measurement uncertainty rarely appears on the resulting curves.

Assessment of strain measurement techniques to characterise mechanical properties of structural steel [PDF]
Engineering Science and Technology, an International Journal, 2014 Strain measurement is important in mechanical testing. A wide variety of techniques exists for measuring strain in the tensile test; namely the strain gauge, extensometer, stress and strain determined by machine crosshead motion, Geometric Moire ...

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

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 ...

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.
