基于宏细观模型的黏弹性复合材料层合板阻尼预测
Damping prediction of viscoelastic composite laminates based on macro and micro models
摘要
Abstract
A finite element method based on macro and micro models was proposed to solve the modal damping of composite laminates.This method takes the modal analysis results of laminated plates as the boundary condition input for a unidirectional fiber RVE model with a viscoelastic matrix.The anisotropic loss factor with frequency and strain dependence is calculated,and the strain energy method is combined to introduce damping that conforms to the actual distribution in the macroscopic model.The modal damping of laminated plates is solved using complex fre-quency analysis steps in finite element software.Compared with existing damping prediction methods,the calculation results of this method have a trend closer to experimental data,and only the material properties of the microscopic components need to be defined to achieve damping prediction of composite materials with any volume fraction and any layer.It has a wider applicability and provides a reference for using general finite element software to analyze various types of composite.关键词
