【 摘 要 】

We have analysed the free vibration responses of the laminated composite plate with delamination numerically and validated with subsequent experiment. In order to compute the numerical frequencies, the delaminated composite plate is modelled with two sub-laminate approaches in the commercial finite element package (ANSYS) using ANSYS parametric design language code in ANSYS environment. For the experimental analysis, the woven Glass/Epoxy composite plate is fabricated using hand layup method with the desired delamination. The natural frequencies of the delaminated plate are also computed experimentally with the help of the vibration analyser (NI-CDAQ) and validated by comparing with the simulation result. Further, the simulation model is extended for various design parameter and discussed in detail.
