Dieses Modell zeigt einen Ansatz zur Ermittlung einer Breitband-Impulsantwort durch Kombination von Raytracing- und Finite-Elemente-Methoden. Die Kombination erfolgt vollständig in COMSOL® unter Verwendung idealisierter Filter. In diesem Beispiel werden die Simulationsergebnisse ... Mehr lesen
The model includes a compilation of benchmark examples included in the text book: Shape Memory Alloys: Modeling and Engineering Applications. D. Lagoudas Ed. Springer 2008. The model shows the thermomechanical properties of a NiTi alloy sample subjected to uniaxial tension-compression ... Mehr lesen
This model demonstrates how to compute the acoustic properties of an acoustic liner with a grazing flow. The liner consists of eight resonators with thin slits. The background grazing flow is at Mach number 0.3. The sound pressure level above the liner is computed and can be compared to ... Mehr lesen
Creep is an inelastic time-dependent deformation which occurs when a material is subjected to stress at sufficiently high temperature, say 40% of the melting point or more. Experimental creep data (using constant stress and temperature) often display three different types of behavior ... Mehr lesen
This example models heat generation in a beam-like structure subjected to small amplitude vibrations. The model computes the linear elastic response in the frequency domain. The transient heat-transfer analysis simulates the slow-rising temperature in the beam using the heat generated ... Mehr lesen
A benchmark model for the fatigue module. A cylindrical test is subjected to non-proportional loading. Three stress based models: Findley, Matake, Normal stress, are compared to analytical values and to each other. The non-smooth behavior of the Matake model is captured and discussed. Mehr lesen
The elastoacoustic effect is a change in the speed of elastic waves that propagate in a structure undergoing static elastic deformations. The effect is used in many ultrasonic techniques for nondestructive testing of prestressed states within structures. This example studies the ... Mehr lesen
A standing contact fatigue test is a procedure used for testing crack growth on the subsurface level. In such a test, a spherical object is pressed against the tested materials and cycled between a high and low compressive load. No translational movement between the two occurs. After a ... 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
In this example, which serves as a tutorial for contact analyses, the insertion of a snap hook in its groove is studied. A linear elastic material model is used. Mehr lesen
