In this tutorial model, a step thrust bearing is topology optimized to maximize the bearing capacity. 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 ...

Chain drives are used for transmitting power from one shaft to another, located at some distance. This example simulates the dynamics of a chain sprocket assembly in 2D. The geometry consists of a roller chain wrapped around two sprockets. Both chain links and sprockets are assumed to be ... En savoir plus
In this example, wrinkling is studied in a cylindrical membrane of nonuniform thickness under axial and pressure loading. The membrane is modeled as an incompressible Mooney–Rivlin material. During axial stretching, certain portions of the membrane undergo wrinkling; however, the ... En savoir plus
This app demonstrates the following: Using the knob form object Updating the geometry by rotating a knob Provides info if the results are above or below certain critical values Many trucks are equipped with cranes for handling loads and such cranes have a number of hydraulic ... En savoir plus
The Whirling of a Uniform Shaft tutorial model shows you how to perform a transient analysis of a uniform shaft under gravity. The shaft is supported by two hydrodynamic bearings at its ends. The gyroscopic effect causes the rotor to whirl about its initial axis and the rotor eventually ... En savoir plus
This tutorial investigates the acoustic properties of a porous layer made of glass wool. The porous material has transverse isotropic properties and is modeled with the full anisotropic poroelastic material model. 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 studies the structural deformation of an aircraft fuselage structure subjected to buckling loads. The structure is an assembly of panels and skin connected by rivets. The Fasteners feature sets up a large number of connections and computes the forces acting on each rivet. En savoir plus
This example uses the Electric Currents in Layered Shells interface and the Layered Shell interface to model a piezoresistive pressure sensor. The tutorial considers the design of the MPX100 series pressure sensors originally manufactured by Motorola Inc. Although the sensor is no ... En savoir plus
In this model, you build and solve a 2D beam model using the 2D Structural Mechanics Beam interface. This model describes the eigenfrequency analysis of a simple geometry. A point mass and point mass moment of inertia are used in the model. The two first eigenfrequencies are compared ... En savoir plus
