Using the method of fictitious load, the author has formulated the governing equations of Reissner's and Kirchhoff's plate of variable thickness, respectively, and solved them by the spline integral equation method of unit rigidity plate. 本文用虚载法分别导出Reissner型和Kirchhoff型变厚板方程,它们各自等价于一块单位刚度板,从而可用等厚板样条积分方程法来求解。
Discussion of solving the complicated circuit with kirchhoff's equation 用基尔霍夫方程组解复杂电路的讨论
On the basis of Kirchhoff's hypothesis and Mindlin's theory as well as by means of Hamilton variational principle, the membrane force, bending moment and governing equation are derived. 分别采用Kirchhoff假设与Mindlin理论,基于Hamilton变分原理,导出了带有表面效应影响的膜力、弯矩和控制方程。
