一般形状を持つFRP積層片持板の振動解析法

抄録

This paper presents an analytical method of solving the free vibration problem of cantilever plates made of laminated composite materials. The analytical approach is based on the well-known Ritz method, with displacement functions in complete power series, and is applied to laminated plates of various shapes with straight-line boundaries. A computer program code was developed to accommodate a wide range of material constants for FRP (fiber reinforced plastic) and a variety of plate planforms. Numerical examples include cantilever plates of triangular, L-shaped and parallelogram planforms.
