Analysis of strain energy of unidirectional composites with interleaved viscoelastic damping layers-PartⅡ：Fundamental Theory and In-plane Strain Energy

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.

Abstract: According to the conclusion of PartⅠ,4kinds 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 in-plane and shear strain energy.
