  • Publication number: 20240295397
    Abstract: Method for identifying a plastic deformation of material of an object in situ using strain sensors operating on the principle of electrical resistive strain gauging, fibre optic measurements using fibre Bragg gratings (FBG), vibrating wire sensors ( )VW, distributed fibre optic sensors (DFOS), inductive, capacitive, or piezoresistive sensors, in which in the monitored area (W) subjected to any load condition, there are placed at least four strain sensors (?s) constituting at least two rosettes (I), (II) turned with respect to each other by any angle (?) other than zero and freely shifted with respect to each other by a vector (V) for measuring any plane strain condition, the rotation angle and the displacement of the rosettes (I), (II) are chosen so that no more than two sensors (?s) between the rosettes are parallel to each other or lie on the same straight line, at least two principal strain states (?1, ?2) and principal stresses (?1, ?2) respectively are determined for the monitored area (A), and by monito

  • Patent number: 10620018
    Abstract: Exemplary embodiments provide for a method for continuous measurement of displacements profile of building structures and a sensor for implementation of this method for repeated, automatic displacements profile measurements of the medium by means of optical fiber elements. This is of particular relevance in engineering structures, engineering structure elements, geotechnical structures. The apparatus is characterized in that the measurement involves a measuring sensor, which is constructed of a core with coupled optical fiber sensing elements for determining the core strains and an optical fiber sensing element for determining temperature, placed freely in an axial channel of the core, making possible to perform measurements in such a way, which that allows for compensation of the influence of sensor temperature.
