Acoustic Radiation Performance of a Composite Laminated Plate Subjected to Local Temperature

Composite structures are extensively applied because of their high specific stiffness-to-weight ratios and other advantages. In various scenarios, composite elastically coupled usually exposed to a nonuniform thermal environment. This paper presents numerical simulation studies on the vibroacoustic characteristics laminated plate with elastic supports subjected local temperature. The stiffness matrix boundary first derived based finite element method, then model is developed calculate acoustic properties structure. A comprehensive study performed highlight effect temperature loading position, range, heated area radiation responses plates different supports. results show that existence stress has great influence structure at low frequencies, which affected by constraints areas.
