Kirsch Infinite Plate Problem

This model describes a static stress analysis to obtain the stress distribution in the vicinity of a small hole in an infinite plate. The model is a classic benchmark and is described in Mechanics of Material, by D. Roylance. The stress level is then compared with the theoretical values.

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.

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 ...

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.

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 ...

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.

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.

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.

Bike Frame Analyzer - new

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 ...
