摘要
根据杆件扭转问题的应力函数理论，构造了以横截面为求解区域的二维有限元法，并采用虚单元法和同值节点法解决了多连通域的计算问题。该方法适用于任何截面的杆件，为计算复杂截面杆件的扭转刚度和应力提供了有效手段。
According to the stress function theory of bar torsion,a 2 -dimensional finite element method is developed which takes the cross- section of bar as solved region.The virtual element and slave node con cept is proposed to deal with the multipleconncted cross-sections.The method can be used to analyze the torsional stiffness and shear stress ,and is applicable to bars with every kind of cross-sections,without a ny limitation of cross-section shapes.
