How to Model the Compression of a Hyperelastic Foam

September 5, 2018

When characterizing hyperelastic materials, how do you ensure accuracy? Here, we show how to model the compression of a sphere made of an elastic foam using experimental data.

Seeing Through Solids: Discovery and Applications of Photoacoustics

August 30, 2018

The field of photoacoustics started with Alexander Graham Bell and some sunlight. Now, photoacoustic imaging is used for nearly anything involving generating images of opaque material samples.

Examining Vibration in a Lumped Model of the Human Body

August 21, 2018

Engineers working to reduce the effects of whole body vibration (WBV) in transportation methods can analyze their systems and designs using a lumped model of the human body.

How Do Chladni Plates Make It Possible to Visualize Sound?

August 17, 2018

Is it possible to see sound? Find out for yourself in this blog post on the acoustics behind Chladni plates.

Examining Heat Transfer in a Friction Stir Welding Process

August 6, 2018

Friction stir welding (FSW) is an efficient, cost effective, and environmentally friendly process that can be optimized by studying the heat transfer involved via modeling.

Analyzing a Loudspeaker Array with a Bessel Panel Benchmark Model

July 23, 2018

Engineers can design optimized loudspeaker arrays and other acoustics systems by analyzing a benchmark model of a Bessel panel system like the one featured in this blog post.

Predicting the Stability of Rotor Systems with the COMSOL® Software

July 20, 2018

Instability in a rotor system can lead to catastrophic failure. Fortunately, engineers can predict the stability of rotor systems by performing stability analyses with the Rotordynamics Module.

Evaluating a Turbocharger Design with Rotordynamics Analysis

July 11, 2018

Like a “turbocharged” cup of coffee, an actual turbocharger also increases speed, but in the operation of a combustion engine, not how fast your morning cup wakes you up.
