摘要
在文献［１］的基础上，进一步考虑系统的运动性态，提出并证明了弹性非保守系统的拟变分原理，并利用该变分原理及有限元法分析薄板的弹性动力学响应问题。结果表明，所提出的变分原理能较好地满足薄板非保守系统的动力学响应数值计算的要求．
Based on Ref.[1],new Quasi-Variational principles for nonconservative elastic systems arepresented by taking the dynamic behaviors of system into account. By means of the Quasi-variational principles thin plate concerning nonconcervative problem are also analyzed. Results show that the method proposed in this paper satisfies the demand of value calculation on dymamic response for nonconcervative elastic systems.
