Isotropic Compression with Modified Cam-Clay Material Model
Isotropic compression is a common material test in soil mechanics. The modified Cam-Clay (MCC) model describes the relation between the void ratio and the logarithm of the pressure. In this example, a cylindrical soil sample under isotropic compression is simulated. It is verified that, ... Read More
Simulating a Corrugated Waveguide and Its Impedance
This example exemplifies how to model the impedance of a waveguide of varying cross sectional area. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Computing the Impedance of a Corrugated Waveguide". Read More
Modeling Irregular Shapes by Using Interpolation and Image Data
This file shows how to create a surface of an irregular shape based on text, image, or elevation data. This approach is best suited for data where the height (or elevation) is a function of x- and y-coordinates. The data is of the Matterhorn, a European mountain located in the Alps. In ... Read More
Model of an Argon/Oxygen Capacitively Coupled Plasma Reactor
This tutorial model solves for a one-dimensional capacitively coupled plasma reactor in a mixture of argon/oxygen. Important aspects and strategies for modeling electronegative discharges are discussed. Read More
Spherical Cap with Central Point Load
This benchmark studies the nonlinear deformation of a spherical cap subjected to point load at center using 2D axisymmetric Solid Mechanics and Shell interfaces. The results from the Shell interface are compared with Solid Mechanics interface as well as with analytical results given in ... Read More
Maximizing the Eigenfrequency of a Shell
This model demonstrates how to use the Polynomial Shell feature to increase the lowest Eigenfrequency of a shell by deforming its shape. Read More
High-Cycle Fatigue Analysis of a Cylindrical Test Specimen
A benchmark model for the fatigue module. A cylindrical test is subjected to non-proportional loading. Three stress based models: Findley, Matake, Normal stress, are compared to analytical values and to each other. The non-smooth behavior of the Matake model is captured and discussed. Read More
Permanent Magnet Motor with Campbell Diagram
The noise emitted from an electrical machine can have many sources. In this example, acoustic noise from vibrations created by magnetic force variation is studied. Such noise is often audible at twice the excitation frequency but can also occur at higher frequencies or harmonics of the ... Read More
Pacemaker Electrode
This model, dealing with the current and potential distribution around one pair of electrodes, demonstrates how to synchronize and modify geometry in Inventor by using the LiveLink interface. Read More
Shape Optimization of a Shell
This model demonstrates how to use the Free Shape Shell feature to increase the stiffness of a shell by deforming its shape. Read More
