Equation-Based Modeling with a Space-Time Discretization
In COMSOL Multiphysics®, almost any expression in a computational model can be modified. For example, using a space-time discretization can make optimization problems easy and fast to implement.
Exploring the Ambiguity of Hardness Numbers with COMSOL®
To help customers easily obtain stress-strain curves from indentation test data, this guest blogger turned to simulation applications and COMSOL Compiler™ — and created a brand new product.
The Growing Use of Simulation in Pharmaceutical Development
Did you know that the development cycle of a drug can take years and cost millions of dollars? Simulation is 1 way to make pharmaceutical development processes faster and more cost effective.
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…
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.
