Delamination or the separation of layers is a common failure mode in laminated composite materials. Various factors, including loading, defects in the material, and environmental conditions can trigger the initiation and propagation of layer separation. This leads to degraded structural ...

Electrical events, such as an overcurrent or overload, can seriously damage electrical circuits or power lines. To avoid expensive replacements of critical parts, electric switch circuit breakers can be installed. These mechanically interrupt the current flow or surge by moving a plunger ... Mehr lesen
Composite laminates are synthetic structures and there is always a possibility to optimize the design in terms of the number of layers, the material of each layer, the thickness of each layer, and the stacking sequence for the specified loading conditions. Designers need to know how safe ... Mehr lesen
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 ... Mehr lesen
In diesem Modell ist ein Knowles-ED23146-Receiver (Miniaturlautsprecher) mit einem Testaufbau verbunden, der aus einem 50 mm (1 mm Durchmesser) Ohrpassstück und einem so genannten 0.4-cc-Koppler besteht. Der Empfänger wird mit einem Lumped-Spice-Netzwerk modelliert und am Röhreneingang ... Mehr lesen
In this tutorial, the eigenmodes and eigenfrequencies of an air bubble in water is modeled and compared with analytical solutions. The effects of surface tension is included and allows to model both the pulsating mode and the surface modes of the bubble. Lastly, the effect of the ... Mehr lesen
This example shows how to perform a fatigue analysis of a structure subjected to harmonic vibrations. The loading is applied at the attachments of the structure, and a frequency sweep is performed to compute the fatigue usage. Mehr lesen
In this tutorial model, you will see how to set up an eigenfrequency analysis of a rotor with multiple disks and bearings. The example illustrates how to use Campbell and stability diagrams to identify the critical speeds and the stability threshold. The rotor is modeled using the Beam ... Mehr lesen
Buckling is a structural instability that can lead to failure of a component even without initial material failure. Computation of the critical buckling loads and mode shapes can therefore be important from a design viewpoint, even though it has previously been determined that the ... Mehr lesen
In this example, the External Stress feature in the Solid Mechanics interface is used to provide the material model with the nonsymmetric stress required in the design of an elastic invisibility cloak. The cloak is a domain with special material properties aimed at shielding a region of ... Mehr lesen
