A Formulation to Evaluate the Pressure Radiated from Thin Body Subjected to the Broadband Random Excitations Based on FAQP Method
A thin-body frequency averaged quadratic pressure (TFAQP) formulation is derived for the numerical solution of the acoustic radiation from thin bodies subjected to broadband random excitations. The singular kernel of 1/r 2 and hypersingular kernel of 1/r 3, respectively, are solved by the explicit evaluation method with constant elements. Numerical example is given to verify the formulation for predicting the pressure radiated from thin bodies under broadband random excitations.
