| 摘 要： | 利用Matlab语言编程对均布荷载作用下的矩形薄板进行有限元分析,求得挠度的数值解.然后以弹性力学中的Kirchhoff薄板理论为基础,提出双三角级数形式的挠度函数,由此挠度函数求得挠度的精确解,将2种方法求解的结果进行比较.结果表明:利用Matlab语言编制的程序作数值计算结果与精确解基本吻合,因此利用Matlab语言编程求解矩形薄板挠度问题的速度相对较快,有益于工程应用.

| Abstract: | The Matlab language programming is used to conduct finite element analysis on rectangular thin plate under the equispaced load effect and obtain the deflection of arithmetical solution.Then according to elasticity theory in Kirchhoff thin steel plate theory,the deflection function of double trigonometric series form is proposed to obtain the exact solution to deflection.The solutions from the two methods are compared and the results indicate that the exact solution accords basically with the numerical resul... |
