- As for side box girder , the elastic theoretical solution has been introduced . the method is based on stress function and regards side box girder as combine of plate element and shell element . then the force and stress formulae for flanges have been derived
对于边箱式截面主梁，本文介绍了弹性理论解法，基于翼板单元应力函数，将边箱梁视为板单元和筒壳单元的组合体，从弹性力学出发，推导出板中法向应力。 - Based on the catastrophic characters of the whole strain energy in truss structural instability , the relationship between the whole strain energy and the stress rate in the link element was educed , and the stress rate criterion for judging the instability of truss structures was built up through analyzing the changing law of stress rate
基于杆系结构发生动力失稳时的总应变能突变特征，推导总应变能同杆单元应力变化率之间的关系，并分析应力变化率的变化规律，建立了判定系结构动力失稳的应力变化率准则。 - Generally , structure ' s stresses , not internal force , can be obtained by analyzing discrete structures with routine solid elements , but internal forces of structure such as moment , axial force and shear force are required in the design criterions which are working in the design of hydraulic structures and industrial and civil structures . a convenient method based on the equilibrium condition of internal force and element ' s stresses is presented in this paper . this method can directly solve constraining internal forces on the designated sections , and then solve the moment , axial force and shear force on the corresponding sections
一般情况下用常规的实体单元对结构进行离散后求解得到的是结构的应力而非内力，而现行水工结构及工业与民用建筑结构设计规范的设计准则主要是建立在结构内力（如弯矩、轴力、剪力等）基础上的，本文采用了一种根据单元应力及内力平衡条件直接求解指定截面上的约束内力，并进而求解相应截面上的弯矩、轴力、剪力等的方法，该方法不需要对应力进行拟合。 - Based on the method of directly assuming rational shear strain and deflection fields , a new generalized conforming triangular , 9 dof thick - thin plate bending element , named tsl - t9 , is successfully constructed using semiloof constrains . its stress solutions are improved by the hybrid post - processing procedure . this element is robust and free of shear locking , and possesses excellent performance for both thin and thick plates
5 .根据一阶剪切变形理论，将gmst18单元发展成为新型三角形复合材料层合壳单元，并利用应力杂交化后处理方法对单元应力进行计算，使单元方便地获得了非常满意的应力分布，特别是横向剪应力分布的解答。 - 5 , such results as the list of the reaction force , deformation figure of the truss the contour of the nodes displacement , the contour of the element stress , and the contour of the node stress , are attained under the static force , the analysis of the finite element show that the maximum stress reaches the value of 285mpa , and then the frame body has the larger stress concentration in this position , if the welding around is not adopted
