This model studies the temperature effects on the viscoelastic stress relaxation in a long thick-walled cylinder. In particular, decay of the stresses under the influence of the temperature field during a period of two hours is studied. A four-term generalized Maxwell model represents ... En savoir plus
This tutorial shows how to evaluate the harmonic response of a structure with a moderately nonlinear behavior. A nonlinear problem can only be solved using time-domain analysis. A way to speed up the computation is to use a linearized frequency response analysis to provide good initial ... En savoir plus
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 app demonstrates: Light theme This app allows you to evaluate cross-section data for a wide range of American and European standard beams. Given a set of forces and moments acting on the section, you can also compute a detailed stress distribution. Calculated cross-section data ... En savoir plus
This example studies the deformation of a hemispherical shell, where the loads cause significant geometric nonlinearity. The maximum deflections are more than two magnitudes larger than the thickness of the shell. The problem is a standard benchmark, used for testing shell formulations ... En savoir plus
This model shows a full vibroacoustic analysis of a loudspeaker including driver, cabinet, and stand. It lets you apply a nominal driving voltage and extract the resulting sound pressure level in the cabinet and in the outside room, as well as the deformation of the cabinet and driver, ...

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
Interference fit is a technique used to join or fit one part over or around another part. The internal part is cooled, so that it shrinks, and is then fitted. Once the part heats up again and expands, a contact pressure builds up at the interface between the two parts. This type of ... En savoir plus
This model demonstrates how to use the Interior Contact feature to model the contact pressure at a bolted joint connecting two copper busbars. The AC current flowing through the assembly is induced to flow close to the outside boundaries of the conductors, but the contact resistance is ... En savoir plus
This model illustrates how to perform prestressed eigenfrequency and frequency response analyses in a contact problem. A circular plate is squeezed between two thicker plates. The peak of the prestressed frequency response analysis is compared with the prestressed eigenfrequencies as ... En savoir plus
