Full-scale strain gauge studies of structures under conditions of high temperatures and elastoplastic deformations
The features of full-scale strain gauge studies of structures operated at temperatures up to 550°C, in which local elastic-plastic deformations occur, are considered. A method for determining the creep of strain gauges based on measuring the output signals during cyclically varying deformation is considered. Algorithms for accounting for errors associated with the creep of strain gauges at nonstationary temperatures are proposed. An algorithm for calculating stresses based on measured deformations at variable elastic and elastic-plastic loading of the structure is determined.
