The four-point bending test is a conventional test method used to test the mechanical properties of materials subjected to bending. It is a reliability test used for semiconductor packaging and assembly. This model demonstrates the stress analysis of an IGBT module subjected to a four ... En savoir plus
This model demonstrates how to simulate surface plasmon polaritons in a thin metal layer embedded in dielectric layers. It calculates the dispersion and propagation length of surface plasmon polaritons as a function of photon energy. En savoir plus
In signal integrity (SI) applications, time-domain reflectometry (TDR) is a useful technique for analyzing the discontinuity in a signal path by observing the reflected signal strength. The reflected signal distorts the input pulse mainly by impedance mismatch if there is no external ... En savoir plus
This model shows how to combine different types of material nonlinearity, such as creep and elastoplasticity. In this specific example you will perform a stress and nonlinear strain analysis on a thick cylinder under a nonproportional loading: an initial temperature increase followed by ... En savoir plus
This example considers the thermal cracking of acetone, which is a key step in the production of acetic anhydride. The gas phase reaction takes place under nonisothermal conditions in a plug-flow reactor. As the cracking chemistry is endothermic, control over the temperature in the ... En savoir plus
This example applies the Electrophoretic Transport and Laminar Flow interfaces to model isoelectric separation in a free-flow electrophoresis device. A stream containing six different ionic species is shown to be divided into pure component streams by means of migrative transport in an ... En savoir plus
This example uses asymptotic techniques to study the radar cross-section (RCS) response of a conductive sphere. The selected physics interface transforms the incident plane-wave field on the boundaries to the far-field using the Stratton–Chu formula. The computed results are compared to ... En savoir plus
This is a model of a simple Sagnac interferometer consisting of two mirrors and a beam splitter arranged in a triangle. The entire modeling domain rotates; as a result, the rays propagating in opposite directions in the triangle have different optical path lengths due to the Sagnac ... En savoir plus
This tutorial shows how to use the Radiative Beam in Absorbing Media interface (Heat Transfer Module) to model the attenuation of a laser light going through a sample of silica glass, and the heat source generated by the absorption. En savoir plus
In this example, an SF6/argon plasma reactor at moderate pressure is studied using a global model. The heavy species heat equation is included. Parametric sweeps for input power and argon mole fraction are computed. En savoir plus
