ANSYS在楔形压弯构件稳定分析中的应用

The application of ANSYS in stability analysis of wedgetype compress-bending members

结合ANSYS程序对楔形压弯构件的平面内稳定承载力进行非线性分析,在引入构件整体缺陷、腹板的局部缺陷以及残余应力的同时,考虑了腹板局部屈曲与构件整体屈曲的相关作用,研究了构件的破坏形式,体现了ANSYS有限元软件的非线性分析功能。

Utilizing ANSYS nonlinear analysis is made on the in-plane stable bearing capacity of wedge-type compress-bending members. Under the conditions taking integral defect, local defect of web plate and residual stress in considerations the interaction between local buckling of web plate and overall buckling of members is studied as well as the failure forms of members, which reveal the functions of ANSYS in nonlinear analysis of structure.
