This model demonstrates 3D topology and shape optimization for an extruded geometry. This can be achieved using equation-based modeling and extrusion operators. The model considers stiffness maximization of a beam subject to a constraint on the mass, but the method can be used with any ... En savoir plus
Surface acoustic phonons and surface roughness have an important effect on the carrier mobility, especially in the thin inversion layer under the gate in MOSFETs. The Lombardi surface mobility model adds surface scattering resulting from these effects to an existing mobility model using ... En savoir plus
A thin-walled container made of rolled steel is subjected to an internal overpressure. As an effect of the manufacturing method, the out-of- plane direction has a higher yield stress than the other two directions. Hill’s orthotropic plasticity is used to model the difference in yield ... En savoir plus
The powder compaction process is becoming common in the manufacturing industry, thanks to its potential to produce components of complex shape and high strength. In this example, the compaction of iron powder to form an axisymmetric rotational flanged component is analyzed with capped ... En savoir plus
An evanescent-mode cavity filter is resonant at a frequency lower than its original fundamental mode frequency. Evanescent mode resonance can be realized by creating a discontinuity or reactance inside the cavity. The basic model was modified by the addition of a metal box at either end ... En savoir plus
Rotating cylinder Hull cells are an important experimental tool in electroplating and electrodeposition and are used for the measurement of nonuniform current distribution, mass transport, and throwing power of plating baths. The model reproduces the results for a commercially available ... En savoir plus
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 ... En savoir plus
Light rail transit (LRT) systems often utilize DC power for train propulsion. In these systems the potential gradients in the rails may induce stray currents, which corrode adjacent metallic structures. In this example, the Cathodic Protection interface, using Edge Electrode nodes, is ... 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
Space charge limited emission is a phenomenon that restricts the current of charged particles that can be released from a surface. As the electron current released by a cathode increases, so does the magnitude of the charge density in the immediate vicinity of the cathode. This ... En savoir plus
