Estimating Hyperelastic Material Parameters via a Lap Joint Shear Test
For rubber, polymers, and biological tissue, the relationship between stress and strain is nonlinear, even at small loads. The lap joint shear test can be used to determine material properties.
Why Do Tennis Rackets Tumble? The Dzhanibekov Effect Explained…
If you toss a cellphone, tennis racket, wingnut, cereal box, or any object with 3 axes of rotation in the air, it will demonstrate this interesting and unusual effect…
How Do Bicycle Pedals Stay On?
Ever wonder why the left pedal of a bike has left-handed threads and the right pedal has right-handed threads, yet the pedals stay on when riding?
A Simulation App for Helical Spring Design and Analysis
Helical springs are found everywhere from medical devices to consumer and industrial products. Despite being commonplace for centuries, the design of a helical spring can be complex.
Optimizing an NIV Mask Design with Multiphysics Simulation
NIV masks offer a form of noninvasive monitoring and ventilation for COVID-19 patients, which lessens the need for ventilators and other mechanical respirators.
What Is the Best Way to Analyze Fuel Tank Vibration?
In a traditional approach for modeling a fuel tank, the fluid mass is dispersed through the tank’s wetted surface. A multiphysics method specifically models the acoustic pressure in the fluid.
Modeling Heat Transfer in Thin Layers via Layered Material Technology
We answer some questions you may have about the Layered Material functionality in the COMSOL® software: What does it do? How do you update existing models? How do simulations benefit from it?
6 Ways Engineers Are Using Simulation to Help the Environment
Energy-efficient buildings and appliances. Safe nuclear waste storage. Well-preserved freshwater lakes. These are just a few examples of how simulation is being used to help the environment.
