Abstract:
The report presents an approximate theory and a computer program for calculating the far field sound radiation patterns from cross stiffened and sandwich cylindrical shells under lateral point loading. The far field radiation patterns are given for a range of low ka. It has been found that a practical structure at low frequencies acts as a dipole and then, as the frequency is increased, transforms into a quadrapole. As the frequency is increased further, the higher lobes come into the picture. Author
