厚板的振动分析

Vibration Analysis of Thick Plate Department Engineering Mechanice

摘要: 在本论文中,作者提出了一个厚板振动分析的精确计算方法。该方法是从考虑1/2E∫_Vσ_z²dV影响的余能变分原理而得到的。文后,给出了计算频率的数值结果,并揭示了Reissner理论与三变量原理之间的内在联系。

Abstract: In this paper,the authors prevent an exact method on the vibration analysis of thick plate based on compementary energy principle considered influence of 1/2E∫_Vσ_z²dV term.At last the numerical results of the frequencgs are given,relationship between Reissner theory and three variations theory has been brought to light.
