Explosive column internal residual stress delamination test method based on optical fiber strain monitoring

The invention discloses an explosive column internal residual stress layer stripping test method based on optical fiber strain monitoring, and the method comprises the specific steps: pasting strain optical fibers at the bottom of an explosive column in the circumferential direction and the axial direction of the side surface of the explosive column at equal intervals, mechanically stripping to a certain depth in the axial direction of the explosive column, and carrying out next layer stripping operation after an optical fiber strain signal is stable. Annular and radial strain signals generated by removing materials through multiple times of stripping are recorded, a response surface function of strain change about internal residual stress in the stripping process is established through finite element analysis, and finally the three-dimensional distribution condition of initial residual stress is reversely deduced based on actually measured strain and the response surface function.
