| Abstract: | Strain gages made of nickel foil are devised for measuring the elastic surface stress of a specimen subjected to repeated loads. Sticking nickel foil on the surface of a specimen, the elastic stress is measured by observing slip-bands in the foil resulting from repeated strains. Calibration studies with rotating-bending tests are performed on round steel bars with nickel foil to determine the applicable test temperatures for the gage, and to establish the relation between the first appearance of slip-bands and the magnitude of cyclic stress. The peak stresses in grooved shafts under bending are measured with the nickel foil gages. The accuracy of the results is examined.Paper was presented at the 1988 SEM Spring Conference on Experimental Mechanics held in Portland, OR on June 5–10. |
