摘要
运用有限元法解出薄壁梁扭转状态下的位移,通过算例与初参数法的结果对比表明有限元法求解的结果和初参数法相近,但其计算过程更简便,而且适当地划分单元可以保证精度,这为薄壁结构进行有限元分析提供方便.
The displacement in the restricted torsion conditions of thin-walled beam with open section was educed by using the finite element method.It is suggested through an example that,the finite element method and the initial parameter method lead to the similar answer when they are used to solve the same question,but the former method is simpler.Moreover,dividing the unit suitably can guarantee the precision,making it convenient to analyze the thin-walled structure with the finite element method.
