Abstract

A semi-analytical finite element method algorithm was established to plot the dispersion curves of isotropic aluminum and orthotropic plates. The curves obtained are compared with those plotted by the DISPERSE software and with previous experimental work. The results showed that the accuracy of the method depends on the number of elements for meshing. To ensure good precision and speed of the method, the number of elements per plate thickness must be optimized.

半解析有限元法模拟正交各向异性板中兰姆波的定量评价

建立了绘制各向同性铝板和正交各向异性板色散曲线的半解析有限元算法。所得到的曲线与分散软件绘制的曲线以及之前的实验结果进行了比较。结果表明，该方法的精度取决于网格单元的数量。为了保证该方法的精度和速度，必须优化每个板厚的单元数。
