Verification Model: Postbuckling Analysis of a Spherical Cap

April 16, 2019

Think about what happens to a soda or beer can when you crush it. This phenomenon is called buckling, in which compressive stress causes sudden failure in a structure.

Defying Gravity with a Realistic Acoustic Levitator Model

March 27, 2019

It’s not just science fiction: Objects really can levitate. 1 way this is possible is by using sound waves to lift and suspend particles midair. Simulation can broaden the use of this technology.

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.

Modeling Fluid-Structure Interaction in Multibody Mechanisms

March 20, 2019

To model advanced FSI scenarios, such as swimming mechanisms or airflow around a wind turbine blade, you can use the Fluid-Structure Interaction, Pair multiphysics coupling.

Evaluating the Necking of an Elastoplastic Metal Bar Benchmark Model

March 18, 2019

To determine the strength of elastoplastic materials, engineers often use uniaxial testing to analyze necking instability. This benchmark model proves that simulation is also a reliable method.

How to Model Different Types of Damping in COMSOL Multiphysics®

March 15, 2019

Structural dynamics analyses can be difficult if you have to account for damping. Get a demonstration of how to use the different numerical models for damping in COMSOL Multiphysics. Part 2 of 2.

Damping in Structural Dynamics: Theory and Sources

March 14, 2019

Here’s your introduction to the theory behind damping in vibrating structures, as well as its sources, including internal losses, friction, sound emission, and more. Part 1 of 2.

Performing a Multiphysics Analysis of a Thermal Microactuator

March 8, 2019

To design an optimized thermal microactuator for use in a specific device, you need to account for tightly coupled electrical, thermal, and structural phenomena in your analysis.
