FEA Studies for the Shell A Thin Wall Region: Run #1: Original run having E=193 GPa Run #2: Modify E of shell A by a thickness ratio of 1.18/1.5. The E of shell A become 152 GPa (Note: The model shell thickness is 1.375”) Run #3: E’s of shells B and C are 145 GPa, the value given by the specification. By modifying the thickness ratio of 1.05/1.375, the E of shell A becomes 111 GPa Run #4: E of shell is 145 GPa except in the shell A thin wall regions, where E=111 GPa
