通过一个计算实例讨论了有限元图谱法的推算精度及其影响因素。分析表明,只要预先编制一系列有代表性的图谱,在实用中对图谱选择恰当,就可用这一简便的方法推算出较为准确的应力值和位移值。
The computational accuracy of the finite element method and its influencing factors are discussed through a calculation example. The analysis shows that as long as a series of representative maps are prepared in advance and the maps are properly selected in practice, a more accurate stress value and displacement value can be calculated using this simple method.
