Eigenfrequency analysis of a conrod showing the torsion angle along the conrod at the lowest eigenfrequency.
The Structural Mechanics Module is dedicated to the analysis of mechanical structures that are subject to static or dynamic loads. You can use this software for a wide range of analysis types, including stationary, transient, eigenmode/modal, parametric, quasi-static, frequency-response, buckling, and prestressed analyses.
The Structural Mechanics Module provides user interfaces for analyses in 2D, 2D axisymmetry, and 3D coordinate systems for solids, shells (3D), plates (2D), trusses (2D, 3D), membranes (2D axisymmetry, 3D), and beams (2D, 3D). These allow for large deformation analysis with geometrical nonlinearity, mechanical contact, thermal strain, piezoelectric materials, and fluid-structure interaction (FSI). If you are looking to perform nonlinear materials analysis, there are two add-on products available to you – the Nonlinear Structural Materials Module and the Geomechanics Module. For fatigue life evaluation, you can leverage the add-on Fatigue Module, while if you are looking to model flexible and rigid body dynamics, the add-on Multibody Dynamics Module is for you. The Structural Mechanics Module also works in tandem with COMSOL Multiphysics and the other application-specific modules to couple structural analysis with a wide range of multiphysics phenomena, including the interaction of mechanical structures with electromagnetic fields, fluid flow, and chemical reactions.
