Acoustic impedance sensitivity approach for defining absorbing material layout using the wave based method

Investigation of thermal effects on the steady-state vibrations of a rectangular plate–cavity system subjected to harmonic loading and static temperature loads using a Wave Based Method

“…The WBM has been used for the DSA of vibro-acoustic systems using the direct differentiation method [46], finite difference method (FDM), and adjoint variable method [35]. In this work, the static temperature load is regarded as the design parameter.…”

“…Among these methods, Wave Based Method (WBM, [21]), a deterministic approach based on the Trefftz method, is an efficient technique to solve mid-frequency dynamic problems. It has been successfully applied to engineering problems, such as acoustic simulations [21][22][23][24], plate bending problems [25][26][27][28][29][30][31][32], vibro-acoustic analyses [33][34][35][36][37], et al The usage of the WBM for vibro-acoustic coupling analysis has been well established by Desmet [21]. Desmet [21] applied the WBM to an interior vibro-acoustic problem by deriving the wave functions for the structural and acoustic field.…”
