異方性積層帯板の調和波伝ぱ

抄録

A numerical method is presented for investigating harmonic waves propagation in arbitrary anisotropic laminated strips. The laminated strip is divided into N elements (along the thickness). The displacement field within each element is approximated by a linear expansion in thickness direction and by series in width direction. The principle of virtual work is applied to establish the eigenvalue equations. As a example, the dispersion relations are determined for unidirectional carbon/epoxy laminated strip and hybrid composite laminated strip which consists of carbon/epoxy and glass/epoxy layers.
