This tutorial model simulates a pair of straight conical bevel gears. The gears are modeled as rigid, but one of the gears is fixed while the other is hinged on a rigid bar. The rigid bar is also hinged at a point lying on the axis of the fixed gear. A transient analysis is performed to ... 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.

This model illustrates the instability of a space arc frame under concentrated vertical loading. The Beam interface is utilized. Two different approaches are used: A full incremental nonlinear analysis, where a small lateral load is applied to break the symmetry of the structure A ... En savoir plus
This model illustrates the modeling of slider motion caused by a base rotation. The motion of the slider is analyzed under various forces such as inertia force, centrifugal force, spring force and damping force. The prismatic joint, which is used to connect the two components, is spring ... En savoir plus

This example demonstrates the use of the Solid-Beam Connection multiphysics coupling to create transitions between the Solid Mechanics and Beam interfaces. Two different connection types are discussed, and a comparison of the stress distributions at the transition is made. En savoir plus
Various boundary conditions are employed in the computation of homogenized properties for heterogeneous materials. The choice between periodic or homogeneous boundary conditions depends on whether the infinitesimal volume is modeled as a repeating unit cell (RUC) or a representative ... En savoir plus
This example demonstrates the wrinkling of a thin rectangular sheet stretched uniaxially. First, a static analysis is performed to determine the region of negative principal stresses without wrinkling. Next, a prestressed buckling analysis is carried out to find out the linearized ...

In this tutorial model, a six step thrust bearing is analyzed. A step thrust bearing consists of a stepped bearing surface on which the end of the shaft rotates. The entire assembly is submerged in a lubricant. The shaft collar is assumed to be spinning without any axial motion in the ... 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
