摘要

本文对硼玻璃钢板在非均匀单轴边缘载荷作用下的自由振动和材料固有阻尼进行了分析研究。首先得到临界屈曲载荷(Pcr)，然后计算FRP板在非均匀单轴边缘载荷的不同载荷比例下的自由振动响应和相应模态指标的固有材料阻尼值。采用应变能法和Reddy's TSDT法分别获得了屈曲载荷和自由振动响应。研究发现，载荷性质和长径比对纤维增强聚合物板的屈曲、自由振动和材料固有阻尼性能有显著影响。

Free vibration and inherent material damping characteristics of boron-FRP plate: influence of non-uniform uniaxial edge loads

The current investigation presents the analytical investigation on free vibration and inherent material damping of boron-FRP plate, subjected to non-uniform uniaxial edge loads. Initially critical buckling load (Pcr) is obtained, then followed by free vibration response and inherent material damping values for corresponding modal indices of the FRP plate is calculated for different load fraction of non-uniform uniaxial edge loads. The buckling load and free vibration response are obtained by using strain energy method and Reddy's TSDT respectively. It is observed that the nature of load and aspect ratio influence the bucking, free vibration and inherent material damping behaviour of the fibre reinforced polymer plate significantly.
