摘要/Abstract

摘要： 研究含蜂窝芯层的压电复合材料层合板的表面局部分层热屈曲,建立压电蜂窝层板模型,应用能量原理,计算在层板子层发生局部分层情况下,热屈曲的临界温度变化值。比较不同情况下屈曲临界温差的变化,分析不同因素对发生热屈曲时临界温度变化的影响。由计算结果可得,不同分层形状以及铺层角度对临界温度变换都会产生影响,其中以椭圆形分层具有最好的稳定性。同时临界温度变化也会随附加电场强度线性变化,在工程应用中可利用施加电场来有效防止压电层板局部分层发生屈曲。

Abstract: In this paper, an investigation is carried out to understand the thermal buckling behavior of local delamination near the surface of laminated piezoelectric composite plates with honeycomb core. The model of piezoelectric composite plates was built. The critical temperatures of laminated plates in the case of local delamination near the surface by making use of the energy principle was calculated. The effect of different factors on thermal buckling by comparing the critical temperatures under different situation was analyzed. It shows that, the different shape of delamination and stacking sequences have impact on critical temperature of thermal buckling. The elliptic delamination has the best stability. Also the critical temperature has a linear variation with electric-field strength. In real application, applying electrical field can prevent the buckling of piezoelectric plates.

Key words: thermal buckling, critical temperature change, honeycomb core, delamination, laminated piezoelectric composite plate
