The proposed method is applicable for the thin-walledmember of any cross section with any boundary condition.
本方法适用于任意横截面形状和任意边界条件的薄壁杆件。
2
A linear function is used to express the warping displacements along the cross section of the thin-walledmember.
本方法采用线性函数作为横截面翘曲位移的插值函数，适用于任意横截面形状和任意边界条件的薄壁杆件。
3
Taking the lateral displacement of the cross section and the longitudinal displacement of nodes as the basic variables the finite element analysis of thin-walledmember structures is formulated.
