All bolts in the model can be specified with the same conditions.Īpplication Library path for an example of automatically detecting bolts in symmetry planes: Structural_Mechanics_Module/Contact_and_Friction/tube_connection Automatic Suppression of Rigid Body Motion This negates having to separately define bolts that have been cut by symmetry planes. The cut bolt is detected and treated as if it were a full bolt. Stress plot of a pretensioned bolt that has been cut by a symmetry plane. Membrane, bending, and peak stresses are reported and stress intensities are computed for each such stress classification line. The new Stress Linearization postprocessing node makes it possible to select the edges on which a stress linearization evaluation is to be performed. Other application areas include computing reinforcement in concrete structures and some types of weld analyses. This type of evaluation is common when analyzing pressure vessels and is described in the ASME standard ASME Boiler & Pressure Vessel Code, Section III, Division 1, Subsection NB. Stress linearization is a postprocessing technique where the stresses through a thin section in a solid model are represented by a constant membrane stress field and a linearly varying bending stress field. Browse all of the new features and functionality in the Structural Mechanics Module below. For users of the Structural Mechanics Module, COMSOL Multiphysics ® version 5.3 brings a modeling technique called stress linearization, a bolt pretension study step, and a boundary condition for rigid body suppression.
