A comparison of elasto-plastic parameters of S355 steel obtained in tensile tests using an extensometer, a strain gauge and an ARAMIS 3D DIC system [PDF]
Archives of Civil Engineering, 2022 The paper presents a comparison of three strain measurement methods. The mechanical parameters of S355 grade steel (yield strength, tensile strength, modulus of elasticity) were determined in tensile tests.

A Partial Elucidation of the Gauge Principle [PDF]
, 2008 The elucidation of the gauge principle "is the most pressing problem in current philosophy of physics" Michael Redhead in 2003. This paper argues for two points that contribute to this elucidation in the context of Yang-Mills theories.

Comparative analysis of the DFB fiber laser and fiber-optic interferometric strain sensors [PDF]
, 2007 The DFB fiber laser strain sensor is shown to provide an improvement in the minimum detectable length change by a factor of 275 at 2 kHz for an applied strain when compared with an interferometric sensor interrogated by at equivalent DFB laser.

Strain Sensor-Inserted Microchannel for Gas Viscosity Measurement
Biosensors, 2023 Quantifying the viscosity of a gas is of great importance in determining its properties and can even be used to identify what the gas is. While many techniques exist for measuring the viscosities of gases, it is still challenging to probe gases with a ...
