A MODEL FOR LAMINATED PLATES USED TO CALCULATE SOUND REFLECTION AND TRANSMISSION

摘要: 本文给出一种层合板的模型,可以用来同时计算声波在层合板上的反射与透射,并且是严格满足层间位移和横向剪应力连续条件,然后给出一系列数值例子,与相应的准确解比较。以及说明在不同情况下声反射和透射的一些特点。

Abstract: A new model for laminated plates is proposed in this paper, which might be used to calculate simultaneously sound reflection and transmission through the plates. Besides, this model satisfies the continuity conditions of the displacements and transverse shearing stresses at the interfaces. At the end some numerical examples are given.
