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

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.
