【 摘 要 】

Considering the stress wave effect, taking into account the axial inertia and the rotational inertia, the buckling control equation of the composite plate subjected to the impact load is obtained by the Hamilton principle. The equation is dimensionless and solved by the differential method, discuss the influence critical length, impact quality and lay-up angle other factors on the dynamic buckling of composite plates. It shows that the change of critical length, impact quality, and the lay-up angle, the modal number, half-wavelength and peak value of the buckling mode change, and the buckling high-order mode is changed. Excitation further illustrates that the stress wave effect and axial inertia have a significant effect on the dynamic buckling of composite plates.
