Anechoic coatings are used on submarines to reduce sonar reflections. This model calculates the reflection, absorption, and transmission properties of an anechoic coating on a steel plate. The calculated results from this sub-model can be used in larger system scale models, for example, ... En savoir plus
These models are featured in the blog post Analyze Violin Tone and Volume with Multiphysics Modeling. One applies acoustic-structure interaction to study how the air mode resonance is affected by the coupled vibrations in the violin body. The other uses a potential flow approximation to ...

Active magnetic bearings are often used for controlling the vibration level in mechanical systems. In this example, a motor driven rotor system in which the speed of the system is gradually increased is considered. The system vibrates due to existing imbalances. As the rotor speed ...

Piezoelectric devices are widely used as sources to generate sound waves or receivers to detect acoustic signals. In applications such as ultrasound imaging and nondestructive testing, the same transducer can be used as a transmitter to send a source signal and receiver to detect ... En savoir plus
A square airbag made of a hyperelastic, compressible neo-Hookean material is inflated using pressurized air. Compressive stresses trigger wrinkling in some regions of the thin airbag. In this example, the wrinkling behavior is modeled using tension field theory, which gives a correct ... En savoir plus
This model analyses the noise generated by an electric motor during its operation at different speeds of rotation. The type of electric motor analyzed, a permanent magnet synchronous motor (PMSM) uses permanent magnets in the rotor and a variable frequency current traveling through the ... En savoir plus
When simulations are involved in the development of mobile devices, consumer electronics, hearing aids, or headsets, it is necessary to consider how the transducers interact with the rest of the system. Here, we show an analysis of the interaction between a vibration isolation mounting ... En savoir plus
In this tutorial model, the flow in a pipe with a bend is computed using the Pipe Flow interface. The computed fluid load is used as input to a stress analysis in the Pipe Mechanics interface. Gravity loads from the pipe and fluid are also taken into account. En savoir plus
Interfacial failure or delamination in a composite material can be simulated with a cohesive zone model (CZM). A key ingredient of a cohesive zone model is a traction-separation law that describes the softening in the cohesive zone near the delamination tip. This example shows the ... En savoir plus
The triaxial test is one of the most common tests used in laboratory soil testing. The soil sample is normally placed inside a rubber membrane and then compressed maintaining a radial pressure. In this model, a vertical displacement and a confinement pressure are applied on the sample ... En savoir plus
