摘要
本文提出一种适用于具有复杂边界条件的矩形板的半解析有限元方法,它是对有限条方法的改进。本方法从结线位移出发构造半解析函数,推导动力平衡方程。给出了几种板的自由振动和静力问题的数值算例,表明本方法具有很好的精度。
A semi-analytical FEM which is a revision of the finite strip method, for analysis of plates with mixed boundary conditions is presented. In this method, the dispacement function of the plate is based on that of the nodal lines, and the dynamic equilibrium equation is derivedaccordingly. Numerical results of the dynamic and static responses of several kinds of plates show the good accuracy of the method offerd.
