Abstract : In this analysis equations are developed to obtain the response of models of deep submergence glass hulls with Adiprene cladding which are subjected to impact loading. Combined stresses in the glass hull, cladding deflection, cladding velocity, impact force and duration of impact are calculated from the impact theory of Hertz (ref. 1), and the shallow shell theory of Reissner (ref. 2) for various initial velocities of impact. Both the analog and the digital computers were utilized in the solution of the equations. Nondimensional scaling equations are developed to predict the response of both the prototype and model.
