The eigenfrequencies of a rotating blade are studied in this benchmark. It shows how stress stiffening and the combined effect from stress stiffening and spin softening affects the fundamental eigenfrequency. High rotational speed in rotating machineries can result in centrifugal forces ... Mehr lesen
In this model the high speed turbulent gas flow in a converging and diverging nozzle is modeled using the High Mach Number Flow interface. The diffuser is transonic in the sense that the flow at the inlet is subsonic, but due to the contraction and the low outlet pressure, the flow ... Mehr lesen
Oberflächenplasmon-Polaritonen (surface plasmon polaritons, SPP) sowie andere Arten von elektromagnetischen Oberflächenwellen sind aufgrund ihrer einzigartigen physikalischen Eigenschaften und ihres Anwendungspotenzials von großem Interesse. Die hier vorgestellten Modelle zeigen, wie die ... Mehr lesen
One method of creating spring-like structures or inducing curvature in thin structures is to plate them to substrates that are under the influence of residual stresses. The plating process can control this stress even for similar materials. One such device is the electrostatically ... Mehr lesen
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 ... Mehr lesen
This tutorial model shows a system consisting of a Helmholtz resonator on the side of a main duct. The resonator volume is partly filled with a porous material. The model computes the reflection, transmission, and absorption of the system. Thermoviscous losses are included in the model ... Mehr lesen
High Cycle Fatigue (HCF) of a spoke in a wheel rim is studied. As the wheel rotates, the stress histories in the structure will become nonproportional. The risk of fatigue is evaluated using the Findley criterion. Mehr lesen
The double barrier structure is of interest because of its application in semiconductor devices such as resonant-tunneling diodes. This verification example demonstrates the Schrödinger Equation interface to set up a simple 1D GaAs/AlGaAs double barrier structure to analyze the ... Mehr lesen
A tapered slot antenna, also known as a Vivaldi antenna, is useful for wide band applications. Here, an exponential function is used for the taper profile. The objective of this model is to compute the far-field pattern and to compute the impedance of the structure. Good matching is ... Mehr lesen
This tutorial presents the averaging models available within the Heat Transfer in Porous Media interface, used to compute the effective thermal conductivity, when the local thermal equilibrium assumption is made. The models are compared for porosities ranging from 0 to 1, and for a ... Mehr lesen
