In diesem Tutorial-Modell wird die Akustik des menschlichen Gehörgangs untersucht. Die Ausgabe umfasst die Eingangsimpedanz und die Übertragungsimpedanz sowie die Pegeltransformation vom Eingang zum Trommelfell. Die verwendete Geometrie des Gehörgangs basiert auf Messungen an ... Mehr lesen
Underground train grids span large areas under London, Paris, New York, and other cities. The building regulations require strict noise standards, and failure to comply could result in significant losses in the market prices of developments. Therefore, train-induced noise has to be ... Mehr lesen
In this model, we use the Pressure Acoustics, Boundary Elements physics interface to analyze the acoustics of a generic head and torso simulator. This is a manikin head used to do standardized measurements for hearing aids, mobile phones, and headphones. The model showcases some ... Mehr lesen
Interference fit is a technique used to join or fit one part over or around another part. The internal part is cooled, so that it shrinks, and is then fitted. Once the part heats up again and expands, a contact pressure builds up at the interface between the two parts. This type of ... Mehr lesen
This model shows how you can implement a user defined hyperelastic material, using the strain density energy function. The model used is a general Mooney–Rivlin hyperelastic material model defined by a polynomial. In this example, you will see two material models based on the defined ... Mehr lesen
When a droplet is placed on a substrate on which surface acoustic waves (SAWs) are traveling, the energy of the SAWs is transferred into the droplet to form an acoustic field. The transferred energy is attenuated and generates a streaming flow. This type of streaming enables contactless ... Mehr lesen
This model demonstrates topology optimization for a problem involving acoustic-structure interaction for a sound partition problem. The objective being to reduce sound transmission for a fixed solid material fraction. The design domain is modeled with a mixed formulation using the Solid ... Mehr lesen
Cross-coupled forces present in a hydrodynamic bearing often act as a negative damping in a rotor. Near the critical speed, this may lead to uncontrolled vibration of the turbocharger causing a risk of bearing failure. In this example, the influence of the cross-coupling forces on the ...

This example uses the Electric Currents in Layered Shells interface and the Layered Shell interface to model a piezoresistive pressure sensor. The tutorial considers the design of the MPX100 series pressure sensors originally manufactured by Motorola Inc. Although the sensor is no ... Mehr lesen
This model demonstrates how to set up a fully coupled poroviscoelastic model of biological tissues. The model is benchmarked by simulating a cyclic uniaxial tension–compression test on human brain tissue. Mehr lesen
