Special panel fixtures developed for verifying integrity of bonds between propellants and insulators in solid-fuel rocket motors by applying, to specimens of propellant and insulator material, stresses similar to those caused by shrinkage during fabrication of motors. Assemblies of fixtures and specimens called "stress-simulating witness panels." Concept also applicable to stress testing of bonds in other manufactured products subject to shrinkage or to swelling.
