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
In this benchmark example, a semi-elliptical crack at the inner surface of a cylinder is studied. The inside of the cylinder and the crack faces are subjected to a pressure load. The J-integral is calculated along the crack front, and the stress intensity factor is then compared with the ... En savoir plus
Reflow soldering is an important process in IC packaging. In reflow soldering, the solder materials are melted to create joints between electrical components and the PCBs for structural and electrical connections. This model demonstrates the process of attaching chips to a PCB by reflow ... En savoir plus
A contactor wedge is subject to a gravity load and is forced to slide due to a boundary load over a rigid target wedge surface, both infinitely wide. Horizontal linear springs are also connected between the left vertical boundary and the ground. This is a large sliding problem including ... En savoir plus
In this example, the coupling between Multibody Dynamics and Rotating Machinery, Magnetic for performing electromagnetic and mechanical analysis is demonstrated. A permanent magnet motor with 10 rotor poles and 12 stator slots is modelled in 2D. The magnets are attached to the ... En savoir plus
The noise emitted from an electrical machine can have many sources. In this example, acoustic noise from vibrations created by magnetic force variation is studied. Such noise is often audible at twice the excitation frequency but can also occur at higher frequencies or harmonics of the ... En savoir plus
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 ... En savoir plus
This example shows how to implement a stress dependent material model. The Young's modulus changes based on the stress value. En savoir plus
This example shows how to model prestressed bolts. The bolt geometry is taken from the Part Libraries. For comparison, one of the bolts is modeled using a thread contact formulation, whereas the other bolt is connected to the bolt hole by a pure continuity condition. The reduced ... En savoir plus
In this example, a lumped model of a vehicle suspension system having 11 degrees of freedom is analyzed. The Mass, Spring, and Damper nodes of the Lumped Mechanical System interface are used to model the wheels, including suspension system as well as the seats with a passenger. The ... En savoir plus
