Analysis Of Vibration Level Of A Perforated Panel Using Finite Element Method

Introduction of perforation into plat-like structures is commonly found as one of practical noise control mechanisms to reduce the sound radiation. However, introduction of holes into the panel reduces its stiffness and hence increases its vibration. Since the effect is lacking, this paper investiga...
