Which Radiation Interface Should I Use for My Heat Transfer Model?

March 4, 2021

Compared to the mechanisms of heat transfer by conduction and convection, heat transfer by radiation has unique characteristics. How should you account for radiation in your heat transfer models?

Modeling Thermomechanical Fatigue in COMSOL Multiphysics®

February 18, 2021

You can analyze thermomechanical fatigue in COMSOL Multiphysics® using experimental data from fatigue testing and material parameters from literature. A guest blogger demonstrates…

Modeling Parts Without Constraints in Your Structural Analyses

January 7, 2021

When building a solid mechanics model, there may be parts with prescribed loads but no constraints that can be reasonably applied. Learn different approaches and considerations for this scenario.

The North Pole Models Product Distribution Challenges for the Holidays

December 18, 2020

Today, a guest blogger from the North Pole discusses using simulation to find out if his boss will be able to fit down all of the chimneys this holiday season.

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.
