Abstract

"Plexiglass models were used to produce Moiré fringes for two different geometrical shapes. The moments in the case of a simply supported rectangular plate with a normal concentrated load were found using the Moiré fringes which directly give the gradients at all points of the surface of the model. The variation of the moments due to a square cutout was also studied by this method. As a check for the experimental method, the analytical solution was presented for the plate without a cut-out. The Moiré method yields moments to an accuracy of 3 to 15 percent, however, care must be taken at the model corners. The technique and apparatus is described, details of experimental technique are given and discussed, and the resultant experimental fringe patterns for simply supported rectangular plates, of different geometry, under different loading conditions, are shown for future study of plates. The complete analysis is given on plates, with and without cutout, with a concentrated load at the mid-point of the edge of the cutout portion parallel to the long side of the plate, and at a corresponding point on the plate without a cutout"--Abstract, page ii.
