AN EXPERIMENTAL STUDY OF STRESSES AT THE INTERFACE OF PROPELLANT GRAINS AND MOTOR CASES DUE TO THERMAL LOADING OF THE SHRINKAGE TYPE. STRESSES IN SQUARE SLABS, WITH DIFFERENT EDGE GEOMETRIES, WHEN BONDED ON ONE FACE TO A RIGID PLATE AND SHRUNK.
Abstract
An approximately square epoxy slab (approx. 14 in x approx. 14 in x 1 in) with four different edge geometries was bonded to a rigid plate on one of its faces. In the process of 'freezing' photoelastic effects a state of restrained shrinkage developed. Slices removed from the slab were used to determine the concentration factors corresponding to the four geometries. (Author)
