Fluid-Structure Interaction with Two Fluid Phases
The following example demonstrates techniques for modeling a fluid-structure interaction containing two fluid phases in COMSOL Multiphysics. It illustrates how a heavier fluid can induce movement in an obstacle using the arbitrary Lagrangian-Eulerian (ALE) technique along with the Two-Phase Flow, Ph...

Piezo-Acoustic Transducer
People that use piezoelectric transducers are interested in phased-array microphone, ultrasound equipment, ink-jet drop actuators, drug discovery, Sonar transducers, bio-imaging and acousto-bio-theraputics. Basically anyone who is trying to create sound in air or liquids turns to a version of this p...

Fluid-Structure Interaction in Aluminum Extrusion
In massive forming processes like rolling or extrusion, metal alloys are deformed in a hot solid state with material flowing under ideally plastic conditions. Such processes can be simulated effectively using computational fluid dynamics, where the material is considered as a fluid with a very high...

Viscoplastic Creep in Solder Joints
This example studies viscoplastic creep in solder joints under thermal loading using the Anand viscoplasticity model, which is suitable for large, isotropic, viscoplastic deformations in combination with small elastic deformations.
The model geometry includes two electronic components (chips) mou...

Elasto-plastic and Fatigue Analyses of a Cylinder with Hole
A load-carrying component of a structure is subjected to multi-axial cyclic loading during which localized yielding of the material occurs.
Due to localized yielding, you can use two methods to obtain the stress and strain distributions for the fatigue law. The first method is an elasto-plastic a...

Heating Circuit
Small-sized heating circuits are used in many applications. For example, in different manufacturing processes, heating circuits are used to heat reactive fluids.
This is a stationary model of a heating circuit, consisting of a thin electrically resistive layer deposited on a quartz glass plate....

Nonlinear Magnetostrictive Transducer
Magnetostrictive transduction is used in sonars, acoustic devices, active vibration and position control and fuel injection systems.
The transducer has a steel housing enclosing a drive coil. A magnetostrictive material is placed in the core which works as an actuator when a magnetic field i...

Structural and Fatigue Analyses of a Shaft with a Fillet
This benchmark model shows how to perform a high-cycle fatigue analysis for nonproportional loading using critical planes.
Two time-dependent loads are applied to the small end of a shaft: a transverse force, causing bending, and a twisting moment.
In this model, a shaft with a fillet is expos...

Structural and Fatigue Analysis of a Car Wheel Rim
This example shows two structural analyses of a car wheel rim.
Firstly, the parametric solver is used to simulate a varying load along the boundary of the rim. The model solves for both the anti-symmetric and symmetric load cases. The two solutions are then combined in MATLAB in order to retrieve...
