初应力对薄板动态特性影响的理论分析与研究

The Influence of Initial Stress on the Vibrational Behaviour of Thin Plates-A Theoretical Analysis and Study

从理论上分析了初应力（或残余应力）对薄板动态特性的影响，建立了相应的有限元方程式。为正确计算分析具有初应力的薄板动态特性提供了理论依据。

The influence of initial stress (residual stress) on the vibrational behaviour of thin plates is analyzed theoretically, and a corresponding finite element equation is established. The results form a theoretical basis for analyzing and calculating the vibrational behaviour of thin plates with initial stresses (residual stresses).
