The Application Gallery features COMSOL Multiphysics® tutorial and demo app files pertinent to the electrical, structural, acoustics, fluid, heat, and chemical disciplines. You can use these examples as a starting point for your own simulation work by downloading the tutorial model or demo app file and its accompanying instructions.
Search for tutorials and apps relevant to your area of expertise via the Quick Search feature. Note that many of the examples featured here can also be accessed via the Application Libraries that are built into the COMSOL Multiphysics® software and available from the File menu.
This model demonstrates the inflation of a rubber balloon with four different hyperelastic material models. The results are compared with the analytical solution for a thin-walled, spherical vessel. Controlling the inflation of hyperelastic balloons is important in clinical ... Read More
In this example, two model for brittle damage are used to evaluate the fracture of a notched concrete beam subjected to three point bending. The results are compared with experimental data. Read More
This example studies viscoplastic creep in solder joints under thermal loading using the Anand viscoplasticity model, which is suitable for large, isotropic, viscoplastic deformations in combination with small elastic deformations. The geometry includes two electronic components (chips) ... Read More
In this example, a benchmark problem in dynamic fracture of brittle materials is analyzed using the AT1 phase-field damage model. An instantaneous tensile load is applied to a planar tension specimen with a pre-existing crack. Initially, the crack propagates perpendicular to the loading ... Read More
This example shows the analysis of a perforated plate loaded into the plastic regime. Part of the example is a benchmark, which you can find in section 7.10 of The Finite Element Method by O.C. Zienkiewicz. The unloading of the plate and residual stresses are also studied. In a second ... Read More
The External Material functionality makes it possible to program your own material models for cases when the built-in material models are not sufficient. For structural mechanics, you have the possibility to either completely define the material model in a domain, or to add an inelastic ... Read More
In this example, a tensile test is simulated at four different strain rates. The Johnson–Cook hardening law is used to model the strain rate dependency of the plastic hardening. The temperature distribution and thermal expansion caused by the heating generated by the plastic ... Read More
In offshore applications, it is sometimes necessary to quickly seal a pipe as part of the prevention of a blowout. This example shows a simulation, in which a circular pipe is squeezed between two flat stiff indenters until it is almost flat. The model serves as an example of an analysis ... Read More
This model shows how to combine different types of material nonlinearity, such as creep and elastoplasticity. In this specific example you will perform a stress and nonlinear strain analysis on a thick cylinder under a nonproportional loading: an initial temperature increase followed by ... Read More
This model demonstrates how to set up a phase field damage multiphysics model to predict crack propagation in thermoelastic solids under large deformations. The crack-driving force depends on the principal stresses, which in turn depend on the temperature distribution in the solid ... Read More
