Making Structures Stronger by Removing Material
To make a structure stronger, sometimes you have to take material away instead of adding more. We go over concepts like fillets, load paths, and displacement control to demonstrate this concept.
Building Roller Chain Geometries in the Multibody Dynamics Module
You can easily set up a geometry model of a roller chain, sprocket, or roller chain sprocket assembly using the built-in parametric geometry parts in the COMSOL Multiphysics Part Library.
Optimizing Composite Wheel Rim Designs with COMSOL Multiphysics®
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.
Happy Birthday, Edith Clarke
Once hired as a “human computer”, electrical engineer Edith Clarke is known for inventing the Clarke Calculator, which solves capacity and inductance calculations for long transmission lines.
