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…
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.
Teaching Transport Phenomena to Engineering Students with Apps
Dr. Amol Deshpande from BITS Pilani, Goa Campus is moving beyond traditional classroom lectures by building simulation apps that students use to visualize heat transfer and fluid flow concepts.
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.
Computing the HRTF of a Scanned Geometry of a Human Head
Designing cochlear implants, hearing aids, headphones, and other audio devices requires precise measurements of the head-related transfer function (HRTF). Simulation and geometry import can help.
