In this example, it is demonstrated how to extend the built-in linear elastic material model to a Cosserat material through the addition of microrotation degrees of freedom. A cylindrical bar under pure torsion is analyzed and the effect of the Cosserat length scale parameter on the ... Mehr lesen
A cable is a structural member which has stiffness only in its tangential direction, but virtually no bending stiffness. When supported only at its two ends it deflects under gravitational load forming a curve known as catenary. This example shows how to model components such as cables, ... Mehr lesen
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 ... Mehr lesen
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 ... Mehr lesen
This example presents a homogenized model of a corrugated sheet based on a unit cell approach. The numerically obtained equivalent stiffness matrices are compared with various analytical models. Two corrugation profiles, trapezoidal and round, are considered in this example. Mehr lesen
The Highly Accelerated Stress Test (HAST) is a testing technique to precipitate failure of electronic devices under elevated temperature and high humidity environment. This model demonstrates the structural analysis of a plastic encapsulated IGBT module under the HAST testing condition. ... Mehr lesen
This model describes a static stress analysis to obtain the stress distribution in the vicinity of a small hole in an infinite plate. The model is a classic benchmark and is described in Mechanics of Material, by D. Roylance. The stress level is then compared with the theoretical values. Mehr lesen
In the surface acoustic waves industry different crystal cuts of piezoelectric materials are used, e.g. 128ᵒ YX LiNbO3, AT&ST quartz, 42ᵒ YX LiTaO3, etc. Direct data isn’t available for all cuts. The standard approach is to use the so-called Euler angle rotation. COMSOL supports it ... Mehr lesen
A benchmark model where a thick plate exposed to pressure on the top surface is analyzed. The solution is compared with a NAFEMS benchmark solution. Mehr lesen
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 ... Mehr lesen
