Keynote Video: Rapid Prototyping for Sonar Systems

December 15, 2020

Engineers at Northrop Grumman follow a 4-part rapid prototyping design phase: Design, manufacturing a prototype, testing and design verification, and manufacturing of the final design.

Exploring the Ambiguity of Hardness Numbers with COMSOL®

September 22, 2020

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.

Implementing a Damage Evolution Law for a Hyperelastic Material

September 8, 2020

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

September 3, 2020

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.

Using the Material Libraries in COMSOL Multiphysics®

February 27, 2020

The built-in material libraries are databases with materials and their associated properties, while the add-on Material Library contains material properties for more than 3800 materials.

Optimizing Composite Wheel Rim Designs with COMSOL Multiphysics®

February 12, 2020

Composite wheel rims are stronger and lighter than their conventional steel and aluminum counterparts. Plus, they offer better acceleration, braking, and cornering on the road.

Keynote Video: Improving Process Understanding with Applications

May 30, 2019

When an organization’s research spans across many industries, consistent product quality becomes the name of the game. That’s why Huntsman Advanced Materials turned to simulation applications.

Modeling Multi-Ply Materials with Composite Materials Technology

March 26, 2019

In a follow-up to a previous blog post on paper mechanics modeling, Eric Linvill of Lightness by Design compares 3 methods of analysis for multi-ply materials such as paperboard.
