Identification of Elastic Parameters for Angle-ply Laminated Plates and Shells

摘要

An inverse analysis method has already been proposed by one of the authors to identify elastic parameters of laminated composite materials using the FEM eigenvalue analysis and the nonlinear optimization method. The purpose of this study is to apply the proposed method to a laminated square plate and a laminated shallow cylindrical shell made of the same composite material. The identified layer of elastic parameters of the plate were compared, and found to agree well with that of the shell.
