How Does This Lip Gloss Appear to Defy Gravity?
We attempt to explain a mysterious, gravity-defying phenomenon involving a viral video, dielectric materials, electrostatics, and lip gloss.
Implementing a Damage Evolution Law for a Hyperelastic Material
By implementing a physically motivated damage evolution law for a hyperelastic material, you can incorporate material softening, creep, and stabilization of hysteresis curves during cycling.
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?
Modeling a Scatterer Near an Optical Waveguide
In the real world, most structures are more complex than a 2D dielectric slab. However, if you’re designing photonic structures, you can learn a lot about wave optics modeling from this example.
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.
