Accelerated Life Testing

Fatigue testing of nonlinear materials with creep mechanism is a time consuming process. In accelerated life testing the experiment time is greatly reduced by subjecting the material to testing conditions in excess of the operating one. In the model an aggressive thermal load cycle is simulated and its effect on the fatigue life of a solder joint is examined. This example demonstrates how to ...

Micropump Mechanism - Fluid-Structure Interaction

Micropumps are key components of microfluidic systems with applications ranging from biological fluid handling to microelectronic cooling. This model simulates the mechanism of a valveless micropump, that is designed to be effective at low Reynolds numbers, overcoming hydrodynamic reversibility. Valveless pumps are often preferred in microfludic systems because they minimize the risk of clogging ...

Hexagonal Grating

A plane wave is incident on a reflecting hexagonal grating. The grating cell consists of a protruding semisphere. The scattering coefficients for the different diffraction orders are calculated for a few different wavelengths.

Acoustic-Solid Interaction with two Perfectly Matched Layers (PMLs)

This small tutorial model shows how to set up a model with both a solid mechanics and a pressure acoustics domain including two perfectly matched layers (PMLs), one for each physics.

Notch Approximation to Low-Cycle Fatigue Analysis of Cylinder with a Hole

A load carrying component of a structure is subjected to multi-axial cyclic loading during which localized yielding of the material occurs. In this model you perform a low cycle fatigue analysis of the part based on the Smith-Watson-Topper (SWT) model. Due to localized yielding, you can use two methods to obtain the stress and strain distributions for the fatigue evaluation. The first method ...

1D Isothermal Nickel-Metal Hydride Battery

This model simulates the discharge of a Nickel-Metal Hydride (NiMH) battery using the Battery with Binary Electrolyte interface. The geometry is in one dimension and the model is isothermal. The model serves as an introduction to NiMH modeling, and can be further extended to include various side reactions.

Outgassing Pipes

This benchmark model computes the pressure in a system of outgassing pipes with a high aspect ratio. The results are compared with a 1D simulation and a Monte-Carlo simulation of the same system from the literature.

Geometric Parameter Optimization of a Tuning Fork

This model computes the fundamental eigenfrequency and eigenmode for a tuning fork that is synchronized from Solid Edge via the LiveLink interface. The length of the fork is then optimized so that the tuning fork sounds the note A, 440 Hz.

Small Concert Hall Analyzer

Designing structures and open spaces with respect to sound quality is important for concert halls, outdoor environments, and even the rooms of a house. Simulating acoustics in the high-frequency limit, where the wavelength is smaller than the geometrical features, can be done with ray acoustics. This application analyzes the acoustics of a small concert hall using the Ray Acoustics physics ...

Inflation of a Spherical Rubber Balloon - Membrane Version

The purpose of this model is to illustrate how the Membrane interface can be used to model thin hyperelastic structures. The example is identical to the Model Library model 'Inflation of a spherical rubber balloon', except that the Membrane interface is used instead of the Solid Mechanics interface.
