Simulating Vibration and Noise in a Washing Machine

January 15, 2015

When designing a washing machine, you must account for a nonuniform distribution of clothing during operation. Simulation can be used to analyze vibration and noise in this household device.

Introducing Nonlinear Elastic Materials

January 9, 2015

Examples of nonlinear elastic material models: Ramberg-Osgood, Duncan-Chang, Hardin-Drnevich, Power law, and more. We discuss how to apply nonlinear elastic materials in your analyses.

Biomechanical Model Evaluates Human Response to Vibrations

December 31, 2014

Take a look at a biomechanical model of the human body in a sitting posture, which can be used to analyze how vibrations (like those from a moving vehicle) affect different parts of the body.
