Cryer's problem is a three-dimensional consolidation benchmark. A porous sphere is subjected to a uniform boundary pressure. The pore pressure at the center of the sphere rises due to the Mandel-Cryer effect that is captured by a two-way coupling between Darcy's law and solid mechanics. Mehr lesen
This model demonstrates topology optimization for a problem involving acoustic-structure interaction for a sound partition problem. The objective being to reduce sound transmission for a fixed solid material fraction. The design domain is modeled with a mixed formulation using the Solid ... Mehr lesen
Ein Hochtöner ist ein Hochfrequenztreiber, der in Lautsprechersystemen verwendet wird. Ein idealer Hochtöner erzeugt unabhängig von der Frequenz einen konstanten Schalldruckpegel in einem bestimmten Abstand vor dem Treiber, d.h. einen flachen Frequenzgang. Im Idealfall behält der ... Mehr lesen
Multilateral wells—those with multiple legs that branch off from a single well—can produce oil efficiently because the legs can tap multiple productive zones and navigate around impermeable ones. Unfortunately, drilling engineers must often mechanically stabilize multilateral wells with ... Mehr lesen
This model shows how to analyze a tuning fork based piezoelectric rate gyroscope. The reverse piezoelectric effect is used to drive an in-plane tuning fork mode. This mode is coupled to an out of plane mode by the Coriolis force and the resulting out of plane motion is sensed by the ... Mehr lesen
This tutorial shows how you can use the Electromechanics interface in COMSOL's MEMS Module to model Electrostriction. Electrostrictive materials (e.g. PMN-PT) exhibit nonlinear strain as a function of electric field. This 2D axisymmetry model uses a parametric sweep of voltage to ... Mehr lesen
Hydrogen embrittlement refers to the degradation of metal ductility due to the absorption of hydrogen. The metal becomes more brittle and thus cracks might initiate at lower stress levels. It is important to estimate hydrogen concentration and the speed at which it diffuses into the ... Mehr lesen
This example demonstrates how to use the Uncertainty Quantification Module by running a series of uncertainty quantification studies for a steel bracket. This type of bracket can be used to install an actuator that is mounted on a pin placed between the two holes in the bracket arms. ... Mehr lesen
The propagation of elastic waves in the ground after a seismic event is simulated using a 2D model. The effect of the ground surface topology on the wave propagation is illustrated when an ideal half-space is modified with the presence of a small mountain. The model is a variation of ... Mehr lesen
A solidly-mounted resonator (SMR) is a piezoelectric MEMS resonator formed on top of an acoustic mirror stack deposited on a thick substrate. This tutorial shows how to simulate an SMR in 3D. In this example, the eigenmodes were computed with varying number of particles attached to the ... Mehr lesen
