In-Plane and Space Truss

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 ...

Bike Frame Analyzer

The reliability of a bike frame can be estimated by analyzing the structural stress subjected to different load cases. This app leverages LiveLink™ for SOLIDWORKS® to interactively update the geometry while computing stress analyses. Using this app, you can easily test different configurations of a bike frame for different cases of dimensions, material, and loads. The app computes the stress ...

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.

Beam Section Calculator

The Beam Section Calculator app allows you to evaluate cross section data for a wide range of American and European standard beams. Given a set of forces and moments acting on the section, you can also compute a detailed stress distribution. Calculated cross section data can also easily be extracted for use as input data for beam analyses in COMSOL Multiphysics. The app is built upon the ...

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.

Thermally Loaded Beam

In this example you will build and solve a 3D beam model using the 3D Beam interface. This model shows how a thermally induced deformation of a beam is modeled. Temperature differences are applied across the top and bottom surfaces as well as the left and right surfaces of the beam. The calculated solution is compared to the analytical solution.

In-Plane Framework with Discrete Mass and Mass Moment of Inertia

In this model, you build and solve a 2D beam model using the 2D Structural Mechanics Beam interface. This model describes the eigenfrequency analysis of a simple geometry. A point mass and point mass moment of inertia are used in the model. The two first eigenfrequencies are compared with the values given by an analytical expression.

Truss Tower Buckling

Buckling analysis is the search for the critical compressive load beyond which structures become unstable. The Truss Tower Buckling analysis application simulates the buckling of a truss tower under vertical compressive loads to provide the critical compressive load. With the app, you can compute and analyze the buckling load for a tower under different conditions of geometry, i.e., various ...

Instability of a Space Arc Frame

This model illustrates the instability of a space arc frame under concentrated vertical loading. A small lateral load is applied to break the symmetry of the structure. Members in the frame are modeled using geometrically nonlinear beam elements. The results are compared with available literature data.

Scordelis-Lo Roof Shell Benchmark

In this example a thin curved membrane is built and solved using the Shell interface. This model is a widely used benchmark model denoted the Scordelis-Lo roof. The computed maximum z-deformation is compared with the value given in Proposed Standard Set of Problems to Test Finite Element Accuracy, Finite Elements in Analysis and Design, 1985.
