The W-section is a W8x40 and the WT-section is a WT4x20. The pretension force applied to the bolt creates a hard contact between the connected elements. –Browse the 4 contact pairs. The analysis accounts for geometric and material nonlinearities, large deformation and Elastic-plastic behaviour. The thermal loadings were of both spatially-uniform and spatially-nonuniform temperatures on the assemblies. It is accessed by clicking the white rectangular icon next to the Help menu by default (on pre tabbed interfaces - in ANSYS 2019R2, the program uses a tabbed interface). 5 there is not GUI support for pretention on theses connections.

The bolts were modelled after the VDI guideline 2230, model class III, as volume without thread. This part of the ANSYS Mechanical study is about Meshing. ANSYS Mechanical - Using Joints Page 16. The so-called Blind Bolts are therefore used as fasteners to alleviate these complexities by allowing for bolted rather than, the-not-so-popular, welded connections to hollow sections. The new feature of Condensed Geometry in recent releases unfortunately does not completely solve the problem; but does get you half way there. Modeling and meshing threaded interfaces is a time consuming and difficult analysis and many times can be unnecessary when the bolt is used simply as a means to transfer loads. In the model below, the left end of the bolt is fixed (all degrees of freedom fixed) and the right end is guided (rotation and x-translation are fixed, but free to translate in y). 1 version 1907 FEM/AFM file, when opening the file in Simcenter 3D 2020. “This causes a bolt preload loss and consequently a loss of function in the bolt connection.
