High temperature fiber optic strain sensing
Two high temperature fiber optic based strain sensors have been developed for use in a coal combustor environment. An intensity based sensor uses losses created by longitudinal misalignment as a sensing mechanism and has a maximum operating temperature of 700°C. An interferometric based sensor …

A dual wavelength fiber optic strain sensing system
… (EFPI) has been extensively used as a strain sensor in various applications. However, like other interferometric sensors, the EFPI suffers from ambiguity in detecting directional changes of the applied perturbation, when the operating point is at a maxima or a minima on the transfer …

Landslide-pipeline interaction for onshore slopes in silty sand
… of soil forces on buried pipe, termed strain demand, can take the form of a simplified Winkler-beam style interaction, more commonly called soil-springs. Despite this simplified concept compared to more numerically intensive coupled continuum analysis, it is favored by industry. The …
