Holographic Applications in Stress Analysis.
Abstract
The report describes some applications of the holographic technique to structural analysis. Experiments were conducted to determine the merits and limitations of the holographic technique as applied to photoelastic and structural models. Improvements in techniques are proposed to relax the requirements on rigid body motion during loading and to eliminate the annealing of slices from photoelastic models. A method is also proposed to improve the intelligibility of combined fringe patterns by virtually eliminating the fringes representing the difference of principal stresses. Both theoretical and experimental methods are used to demonstrate the proposed new techniques. The report identifies those problem areas which are of interest to the Navy and can be solved very effectively by the use of holography. (Author)
