Analyzing Slope Stability Through the Shear Strength Reduction Method

May 28, 2019

Dams that are poorly designed or constructed are likely to fail. However, geotechnical engineers can account for the stability and reliability of a dam long before the structure is even built.

Evaluating the Impact of Bearing Misalignment on Rotor Vibration

May 14, 2019

Bearings are found in devices ranging from MEMS and turbines to electric motors and even ships. How we account for a bearing’s misalignment (and the resulting rotor vibration) depends on its use.

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.
