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 ... En savoir plus
This model shows how to set up a uniaxial compression test on a prestressed soil sample. Due to uniaxial compression and simple initial stress values, it is possible to determine the vertical yield stress analytically. The soil sample is modeled with soil plasticity and the Mohr–Coulomb ... En savoir plus
This model describes the pressure wave propagation in a muffler for an internal combustion engine. The purpose of the model is to show how to analyze both inductive and resistive damping in pressure acoustics as well as coupling the fluid to the surrounding elastic shell structure of the ...

This example showcases a helical planetary gear train composed of a sun gear, ring gear, carrier, and five planet gears. Three cases are analyzed by in turn fixing the ring gear, sun gear, and carrier. For each configuration, a transient multibody analysis is performed to determine the ... En savoir plus
Fatigue testing of nonlinear materials with creep mechanism is a time-consuming process. In accelerated life testing the experiment time is greatly reduced by subjecting the material to testing conditions in excess of the operating one. In the model an aggressive thermal load cycle is ... En savoir plus
This model demonstrates how to set up a dynamic simulation that includes several contact interactions, including friction, using a single general contact pair. The dynamics is solved using explicit time stepping. En savoir plus
This example shows how to perform a High Cycle Fatigue (HCF) analysis with a non-proportional load history caused by a transversal force and a torque which are applied in different combinations. Three different fatigue models (Findley, Matake, and Dang Van) are compared. En savoir plus
This model describes a static stress analysis to obtain the stress distribution in the vicinity of a small hole in an infinite plate. The model is a classic benchmark and is described in Mechanics of Material, by D. Roylance. The stress level is then compared with the theoretical values. En savoir plus
In this model, two fluids are separated by a multilayer solid elastic structure. An acoustic pressure wave impacts the structure resulting in a reflected wave and a transmitted wave with a loss through the structure. This model investigates the transmission loss through the structure. ... En savoir plus
This example shows how to set up an ionic polymer-metal composite (IPMC) as an actuator for a robotic manta ray. Two IPCM beams are integrated into the fin and can be controlled independently. The chemomechanical effect is achieved with the Shrinkage and Swelling multiphysics ... En savoir plus
