In this example, triaxial and oedometer tests are simulated using the Hardening Soil material model. Both tests exhibit a hyperbolic stress–strain relationship. For the triaxial test, it is confirmed that the axial stress approaches the analytical failure stress asymptotically. In the ... Mehr lesen
Dieses Beispiel veranschaulicht die Modellierung von Vibrationen und Geräuschen in einem 5-Gang-Synchronisationsgetriebe eines Fahrzeugs mit Schaltgetriebe. Es wird eine transiente Mehrkörperanalyse durchgeführt, um die Getriebevibrationen für die angegebene Motordrehzahl und externe ... Mehr lesen
This is a model of a simple photoacoustic (or optoacoustic) resonator. A pulsating laser heats a gas causing expansion and contraction and thus creates pressure waves. Such devices are used as sensors for measuring material parameters of the gas inside the resonator. The resonance ... Mehr lesen
In this example, a settlement and heave analysis of a shallow foundation resting on an unsaturated soil stratum is conducted with the Modified Cam-Clay and Extended Barcelona Basic soil models. The effect of pore suction due to movements in the phreatic line and the resulting settlement ... 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
This example shows how to compute deformations caused by secondary creep in a turbine stator blade. The creep rate is highly influenced by temperature, and the deformation and stress relaxation is thus controlled by the temperature field. Mehr lesen
In this model, two fluids are separated by a solid elastic structure. An acoustic pressure wave impacts the structure resulting in a reflected wave and a wave transmitted with a loss through the structure. This model investigates the transmission loss through the structure. The effects ... Mehr lesen
See how to perform a vibration analysis of the crankshaft of a 3-cylinder reciprocating engine in this tutorial model. Due to the eccentricity of the crank-pin and balance masses on the crankshaft, it undergoes self-excited vibration under rotation. The crankshaft is modeled using solid ... Mehr lesen
This example reproduces a NAFEMS benchmark in which a plate with an angle crack is subjected to tensile loading. The J-integral is calculated and the stress intensity factors for Mode I and Mode II are compared to the benchmark results for several crack angles. Mehr lesen
This conceptual example shows how to calculate critical points in models with contact. The model consists of a block modeled with the Solid Mechanics interface pressing on an arch modeled with the Shell interface. The contact problem is solved using the augmented Lagrangian method.
