Abstract:

Stress analysis procedures are presented for fibre-reinforced metallic rocket motor cases using finite-element and photoelastic techniques. These techniques enable analyses of the initial widing process, inertia and pressurisation due to firing to be performed. Certain simplifications and assumptions are introduced to resolve the complicating effects of the fibre overwind and the in-flight loadings. A comparison between the two metods for a typical motor is considered.
