Book excerpt: "An experimental and analytical program was conducted to simulate the separation of the service module bay 4 cover panel from the Apollo 13 spacecraft which occurred during its flight accident. The study was also intended to establish failure mechanisms, pressure distributions, and pressure time histories that would explain the essentially complete separation that was observed in the photographs taken by the Apollo 13 crew. Complete separations of both isotropic and sandwich one-half-scale panel models from a boilerplate test fixture were achieved by rapidly pressurizing the oxygen shelf space with air in a vacuum environment. The sandwich panels tested were most representative of flight hardware. One particular sandwich panel separated as a result of a non-uniform pressure distribution of over 40 psi in the oxygen shelf space 20 milliseconds after start of pressurization; this result was the one most nearly consistent with known flight events. A similar test at slightly lower pressure did not separate the panel; thus, the separation pressure distribution and time history boundary was established.--P. [i].
