THE SPHERICAL ACRYLIC PRESSURE HULL FOR HYDROSPACE APPLICATION. PART III. COMPARISON OF EXPERIMENTAL AND ANALYTICAL STRESS EVALUATIONS FOR PROTOTYPE NEMO CAPSULE.
Abstract
A comparison is presented of results obtained from analytical and experimental stress analyses of the NEMO pressure hull (an acrylic submersible with steel polar penetrations). The general procedures of the analytical investigation are reviewed and the assumptions stated. Excellent agreement between the two sets of results was observed for the acrylic portion of the hull. Due to the severe structural simplification necessary in the analytical simulation of the steel polar penetrations, discrepancies were noted in the two sets of stresses obtained in these regions; general trends were, however, similar. It was concluded that the acrylic to steel transitions incorporated in the prototype design provide an optimum transfer of load without inducing a concentration of stresses. (Author)
