This example illustrates how to model a barrel hinge connecting two solid objects in an assembly. In this model, the details of the connection are not the focus of the analysis, therefore, the hinge joint is modeled using a Joint feature in the Multibody Dynamics Module. The connected ...

In this example, the transient response of a shallow foundation resting on an unsaturated soil stratum is investigated. The changes in pore suction due to water infiltration and evaporation are analyzed using the Extended Barcelona Basic soil model. The results show how the deformation ... En savoir plus
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. En savoir plus
Piezoelectric devices are widely used as sources to generate sound waves or receivers to detect acoustic signals. In applications such as ultrasound imaging and nondestructive testing, the same transducer can be used as a transmitter to send a source signal and receiver to detect ... En savoir plus
An AC contactor is a particular type of magnetic switch device, which is activated by a primary coil fed by an alternating current. Unlike DC switches, such devices can suffer from a tendency to reopen when the AC current crosses zero. The addition of a shading coil that supports ... En savoir plus
This example benchmarks a NAFEMS validation model of a friction contact problem with an elastoplastic material model. A thin metal sheet is forced into a die by a punch. Both the compressing displacement and the release of the punch are modeled in order to compute the forming angle (at ... En savoir plus
Active magnetic bearings are often used for controlling the vibration level in mechanical systems. In this example, a motor driven rotor system in which the speed of the system is gradually increased is considered. The system vibrates due to existing imbalances. As the rotor speed ...

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 ... En savoir plus
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 ...

This is a benchmark model for rigid body dynamics. This model simulates the dynamic behavior of "Andrew’s squeezing mechanism", which is force driven and requires a very small time scale. Various angles in the mechanism are compared with the results from the reference. En savoir plus
