变厚度圆薄板的大挠度问题

LARGE DEFLECTION PROBLEM OF CIRCULARPLATE WITH VARIBLE THICKNESS

文章用插值矩阵法的常微分方程求解器求解变厚度圆薄板大挠度弯曲问题，提出了对一般方程正则奇点的处理途径。该法获得的板位移、内力有相同的精度。

This paper applies an ordinary differential equation (ODE) solver of interpolating matrix method to calculate large deflection of thin circular plate with varible thickness. A process for tackling regular singularity of the ODEs is proposed. The present method gives the same high accuracy for both the displacements and the internal forces of the plate.
