AN EXPERIMENTAL STUDY OF STRESSES AT THE INTERFACE OF PROPELLANT GRAINS AND MOTOR CASES DUE TO THERMAL LOADING OF THE SHRINKAGE TYPE.

Abstract

The stresses present at the interface between the long edge of a strip and a rigid bar to which the strip is bonded, were determined using photoelasticity. The loading is produced by the restrained shrinkage of the strip. The short ends of the strip have fillets of different configurations. Use is made of a newly developed technique to simulate the two-dimensional state of stress at the interface. The shape exhibiting the smallest stress concentration factor was obtained. (Author)
