| Abstract: | In this paper, the calibration of fringe values for photoelastic composite materials with residual stresses is studied in detail. A method is proposed for f_LT calibration by using a circular dish specimen, in which residual stresses are existed. Calibration is also made by using a tensile specimen. Both results are coincidental. Aside from these, it may be worth to mention that the calibrating experiments have the function to check up on themselves. |
