Numerical and Experimental Stress Analysis Studies of Thin-Walled Oblate and Prolate Hemispheroidal Domes and Panel Structures for Sonar Systems
As part of a study and design of new sonar systems a stress analysis of domes and acoustic panels was undertaken. Such structures, having suitable acoustic transparency, provide hydrodynamic envelopes to transducer arrays. The acoustic transparency is affected by both the material properties and the shape and thickness of the dome. The domes are seldom subjected solely to hydrostatic pressures, but are considerably loaded by hydrodynamic pressures.
