Thin vs Thick Case Assumption: thin case assumption can be used if  

Booster

Booster thin case assumption if t < 0.3"

Calculated with thin case assumption -> safety factor = 2, case thickness = 0.343"

Move onto thick case assumption -> safety factor = 2, case thickness = 0.362"

Sustainer

Sustainer thin case assumption if t < 0.2"

Calculated with thin case assumption -> safety factor = 2, case thickness = 0.229"

Calculated with thick case assumption -> safety factor = 2, case thickness = 0.241"
