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 more information on this feature, see the COMSOL Desktop ® Updates.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. This makes it possible to use these functions when defining parameters that are used, for example, for creating geometries and meshes.

Improvements to Adding Functions Defined by M-Files in the MATLAB ® Software to Modelsįunctions defined under the Global Definitions in a COMSOL Multiphysics ® model, including those functions that are defined by M-files in MATLAB ®, are now available for use in all text fields and in table cells that previously supported the use of global parameters. You can also use it to clear a thumbnail, if so desired. The wrapper function mphthumbnail can now directly use the graphics displayed in a MATLAB ® figure window for creating a model thumbnail that can be saved when the model file is saved.
The wrapper function mphmesh has improved support for views and supports the hiding of geometric entities. This makes it easier to switch between plots while maintaining viewpoints for the camera as you switch. The camera positions are also stored when switching between different plots in the figure window.Ī new menu and a toolbar are added to the MATLAB ® figure window generated with mphplot(model). With buttons on the toolbar, you can switch lights on/off and switch between views. Using mphplot(model) you can now generate a MATLAB ® figure window where you can easily switch between geometry, mesh, and result plots in the model, all within the same window. For more information on model reduction, see the Studies and Solvers Updates. The extracted state-space matrices can be used for simulation, control design, and other types of model analyses. The new wrapper function mphreduction makes it possible to extract reduced-order state-space matrices from a time-dependent model. Installed with the COMSOL Client, the shortcut for starting the COMSOL Client with MATLAB ® brings up the Connect to COMSOL Server™ window that you can use to establish a connection to COMSOL Server™ and start the COMSOL Client inside MATLAB ®.
