Tapered Cantilever with Two Load Cases

This example shows a 2D plane stress model of a thin tapered cantilever. Different boundary and load scenarios are examined. It is demonstrated how to apply and how to evaluate different load and constraint groups. Resulting stresses are compared to NAFEMS benchmark values and they are found to be in good agreement.

Pacemaker Electrode, Modeled with LiveLink for Creo Parametric

This model, dealing with the current and potential distribution around one pair of electrodes, demonstrates how to synchronize and modify geometry in Creo Parametric by using the LiveLink interface.

Michelson Interferometer

This model couples the Heat Transfer in Solids, Solid Mechanics and Geometrical Optics interfaces to compute the effect of thermal expansion of optical components on the interference pattern displayed by a Michelson interferometer.

Detecting the Orientation of a Metallic Cylinder Embedded in a Dielectric Shell

A metallic cylindrical rod is hidden inside a spherical dielectric shell and its orientation is unknown. By studying the polarization-dependent scattered field of a cylindrical object and performing a parametric sweep as a function of polarization angle, the rod is detected for the polarization angle where the scattered field is highest. The model uses a linearly polarized plane wave for the ...

Mixed-Mode Debonding of a Laminated Composite

Interfacial failure by delamination or debonding can be simulated with a Cohesive Zone Model (CZM). This example shows the implementation of a CZM with a bilinear traction-separation law. It is used to predict the mixed-mode softening onset and delamination propagation in a composite material.

1D Step Bearing

This benchmark model computes the load-carrying capacity of a one dimensional hydrodynamic step bearing. The results are compared with analytic expressions obtained by solving the Reynolds equations directly in this simple case.

Image Import: Homogenized Pore Scale Flow and Thermal Conduction

You can now use image data to represent 2D material distributions or to identify regions with different materials by their color or gray scale. Images used in this way can have many origins such as scanning electron microscope (SEM), computed tomography (CT), or magnetic resonance imaging (MRI). An important application of image import is for easy computation of equivalent volume-averaged ...

Transverse Modes for a Symmetric Laser Cavity

This model demonstrates how a nonlinear equation system can be setup to solve for the eigenfrequencies of a symmetric laser cavity. The model uses the bidirectional formulation of the Electromagnetic Waves, Beam Envelopes physics interface. The computed eigenfrequencies are verified with values from analytical expressions.

Diverging Duct

When the diameter of a pipe suddenly increases, the area available for flow increases. Fluid with relatively high velocity will decelerate into a relatively slow moving fluid. Depending on the Reynolds number, this can cause turbulence and much of the excess in kinetic energy is converted into heat and therefore wasted. If the change of the cross-section is gradual, the kinetic energy can be ...
