Hydrostatic Pressure Tests on Thin Rectangular Diaphragms 84 Inches by 54 Inches.

摘要

Hydrostatic-pressure tests of thin, clamped, rectangular diaphragms 84 inches by 54 inches were conducted in connection with the general underwater-explosion research program. Data such as profiles of deflected diaphragms, curves of center deflection against pressure, thickness, horizontal displacement, strain, volume of displacement of deflected diaphragms, and energy absorbed were obtained for each of the four diaphragms tested. The results of these tests were compared with results of similar tests on small diaphragms and with a theory for rectangular diaphragms under hydrostatic pressure previously developed at the Taylor Model Basin. The energy absorbed by the large diaphragms when compared with the energy absorbed by the small diaphragms was less than had been expected. (Author)
