This model demonstrates how to perform a hearing aid acoustic feedback response analysis, including both the in-ear hearing aid and the hearing aid cassette. The hearing aid modeled is a ReSound OMNIA™ device from GN Hearing A/S. The hearing aid is tested on a combined pinna and ear ... En savoir plus
This model uses the Semiconductor and RF modules to describe a photoconductive antenna (PCA). A laser pulse is applied on the surface of undoped LT-GaAs to generate electron-hole-pairs, which move under the influence of an external E-field creating a transient electric current pulse. ...

The metal-silicon-oxide (MOS) structure is the fundamental building block for many silicon planar devices. Its capacitance measurements provide a wealth of insight into the working principles of such devices. This tutorial constructs a simple 1D model of a MOS capacitor (MOSCAP). Both ... En savoir plus
Composite laminates are synthetic structures and there is always a possibility to optimize the design in terms of the number of layers, the material of each layer, the thickness of each layer, and the stacking sequence for the specified loading conditions. Designers need to know how safe ... En savoir plus
Anisotropic hyperelastic materials are used for modeling collagenous soft tissue in arterial walls. The Arterial Wall Mechanics application describes a section of an artery based on the Holzapfel–Gasser-Ogden hyperelastic material model. In this example the dynamic behavior of the artery ...

This tutorial illustrates how to use a reduced order model to compute the response of a structure subjected to three simultaneous loads having independent time histories. Reduced order models provide an efficient way to analyze problems within linear structural dynamics. En savoir plus
In this time-dependent model, a silica block of glass, coated with a thin copper layer is subjected to a heat flux. Copper is a highly conductive material, while the silica glass is of poor thermal conductivity, which sets up an highly-varied temperature differential. The model must ... En savoir plus
This example demonstrates how to model moisture transfer and induced swelling in a paperboard roll subject to varying ambient conditions. The material properties of the paperboard are anisotropic. En savoir plus
The Thermal Actuator Surrogate Model Application demonstrates how the computational speed can be increased with the use of a surrogate model. This app demonstrates the following: Adjusting input parameters via sliders, with near-instantaneous updates to the solution retrieved from the ... En savoir plus
When a linear guide is loaded above the manufacturer's specification limit, one concern is whether the contact loads will introduce fatigue spalling. In this system analysis, the entire guide has been analyzed and the mostly damaging contact load has been identified to occur on a rail ... En savoir plus
