GIS pipeline temperature compensation corrugated pipe residual fatigue life evaluation method and storage medium

The invention belongs to the field of material performance evaluation, and relates to a GIS pipeline temperature compensation corrugated pipe residual fatigue life evaluation method and a storage medium. Based on finite element simulation analysis data, corrugated pipe material stress fatigue life data and actually measured GIS pipeline temperature or corrugated pipe axial deformation of the GIS pipeline temperature compensation corrugated pipe under the action of internal pressure and axial tension compression load, fatigue damage generated by thermal expansion and cold contraction of the temperature compensation corrugated pipe every day is calculated, and the residual fatigue life of the temperature compensation corrugated pipe is evaluated. According to the method, the finite element method is adopted to pre-calculate the stress components of the dangerous area of the temperature compensation corrugated pipe under the internal pressure load effect and the axial deformation load effect caused by thermal ex
