A NEW EXPERIMENTAL STRESS-OPTIC METHOD: STRESS-HOLO- INTERFEROMETRY

THE APPLICATION IS DESCRIBED OF A NEW INTERFEROMETRIC METHOD BY HOLOGRAPHY TO PHOTELASTICITY. INTERFEROMETRIC PHOTOELASTICITY IS A WELL ESTABLISHED AND ELEGANT METHOD, HOWEVER, ITS USE IS STILL NOT COMMONPLACE IN LABORATORIES IN STRESS-OPTICS. IN THE PAST FEW YEARS, THERE HAS BEEN A RAPID GROWTH IN HOLOGRAPHIC ACTIVITIES. THE STRESS-OPTIC METHOD DESCRIBED IN THIS PAPER SHOWS AN ALTERNATE (HOLOGRAPHIC) METHOD FOR DETERMINING BOTH ISOCHROMATIC AND ISOPACHIC INTERFERENCE FAMILIES, THUS ENABLING A RELATIVELY EASY AND QUICK SOLUTION TO PLANE-ELASTICITY PROBLEMS. IT IS ALSO SHOWN HOW THE TWO MATERIAL CONSTANTS WHICH ARE REQUIRED CAN BE DETERMINED SIMULTANEOUSLY WITH A SINGLE CALIBRATION TEST. /AUTHOR/
