This model analyzes Joule heating and thermal expansion in a bond wire in an LED. Its purpose is to estimate the temperature increase and the resulting mechanical stresses in the bond wire due to thermal expansion. The magnitude of these stresses can be used to assess the risk of fatigue ... En savoir plus
In this example you will build and solve a 3D beam model using the 3D Beam interface. This model shows how a thermally induced deformation of a beam is modeled. Temperature differences are applied across the top and bottom surfaces as well as the left and right surfaces of the beam. ... 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 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
Micromirrors are used in certain MEMS devices to control optic elements. This example model illustrates a mirror that is initially actuated for a short time and then exhibits damped vibrations. It simulates a vibrating micromirror surrounded by air and uses the Thermoviscous Acoustics, ... En savoir plus
As integrated circuit (IC) technology advances, with circuits becoming more powerful and compact, it is increasingly important to identify and prevent any cause of circuit failure. One particularly critical factor contributing to circuit failure is electromigration within the ... En savoir plus
The katana is a legendary Japanese sword used by the samurai in olden days. Here, we present a simple model where we simulate a differential hardening process to explore some of the features of the katana.
