Homogenisation of viscoelastic damping in unidirectional composites under longitudinal shear

摘要

Explicit expressions for the complex longitudinal shear moduli of viscoelastic composites with arbitrary symmetric structure are obtained. Specific formulas of dissipative properties are obtained for tetragonal composites with elliptic and rectangular fibre cross-sections, as well as for hexagonal (not necessarily regular), composites with elliptic fibre cross-section. The correspondence principle and the duality rule are used. The results of calculations for particular cases agree well with the known published data. (C) 2017 Elsevier Ltd. All rights reserved.
