摘　　要：本文利用PartⅠ中的结论,分析以下4个方面的应变能:广义正交各向异性层在xz方向的切应力应变能;广义正交各向异性层在yz方向的切应力应变能;粘弹性层在xz方向的切应力应变能;粘弹性层在yz方向的切应力应变能。夹杂的粘弹性阻尼材料作为各向同性材料处理。最后求出了整个单层板夹杂粘弹性阻尼材料的总应变能。According to the conclusion of Part Ⅰ , 4 kinds of shear strain energy are analyzed. They are xz -shear strain energy stored in unidirectional composite layers, yz - shear strain energy stored in unidirectional composite layers, xz - shear strain energy stored in interleaved viscoelastic layers, yz - shear strain energy stored in interleaved viscoelastic layers. The interleaved viscoelastic layers are treated as isotropic materials. The total strain energy of unidirectional composites with interleaved viscoelastic is obtained, including inplane and shear strain energy.
