Assembly with a Hinge

In mechanical assemblies, parts are sometimes connected so that they are free to move relative to each other in one or more degrees of freedom. Examples of such connections are ball joints, hinges, and different types of bearings. If the details of the connection are not the subjects of the analysis, it is often possible to model the connection using the Rigid Connector feature in COMSOL ...

In-Plane and Space Truss -A Linear Analysis

Trusses are elements which can only sustain axial forces. You can use trusses to model truss works where the edges are straight as well structures like sagging cables. In the following example you first build and solve a simple 2D truss model using the 2D Truss interface. Later on, you analyze a 3D variant of the same problem using the 3D Truss interface. This model calculates the deformation ...

Wrapped Thick Cylinder under Pressure and Thermal Loading

This model is compared to a NAFEMS benchmark for composite material modeling, No R0031/2. The geometry is a long, thick, and hollow cylinder consisting of two layers, where an internal pressure is applied. The inner layer is made from an isotropic material, while the outer layer is made from an orthotropic material. This material's properties are equal in the radial and axial directions, yet ...

Critical Frequencies for a Rotor

The rotor in an electric motor is analyzed. In the design of a motor it is important that no eigenfrequencies for the rotor lie within the operating interval of the revolution speed (in revolutions / second) for the motor. If the eigenfrequencies of the rotor lie in this interval then this shortens the engines lifetime, and can sometimes even lead to dysfunction and breakdown. This 3d model of ...

Pinched Hemispherical Shell

This example studies the deformation of a hemispherical shell, where the loads cause significant geometric nonlinearity. The maximum deflections are more than two magnitudes larger than the thickness of the shell. The problem is a standard benchmark, used for testing shell formulations in a case which contains membrane and bending action, as well as large rigid body rotation.

Shift into gear

This model demonstrates the ability to simulate Multibody Dynamics in COMSOL. It comprises a multilink mechanism that is used in an antique automobile as a gearshift lever. It was created out of curiosity to find out how large forces are on the individual components. The model uses flexible parts, i.e. the Structural Mechanics Module was used along with the Multibody Dynamics Module.

Thick Wall Cylinder Benchmark Problem

A thick wall cylinder is exposed to both internal and external pressure and thermal load. The model is both plane and axisymmetric. The results are compared to the analytic solution.

Stress Analysis of an Elliptic Membrane

This is a benchmark model for a plane stress problem. The accuracy of the computed stress concentration is evaluated, and a mesh convergence study is performed for different element types.
