The Physics of a Hopping Hoop
Have you heard of the hopping hoop? This problem has interested the minds of researchers and engineers for the last half-century. Let’s see how modeling can provide insight into this age-old case.
New Functionality for Buckling Analysis in COMSOL Multiphysics®
COMSOL Multiphysics® version 6.1 introduces functionality for handling a combination of fixed and varying loads in a buckling analysis. Get the details here.
How to Evaluate Stresses in COMSOL Multiphysics®

What Is the Difference Between Plane Stress and Plane Strain?
We go over the formulations and constitutive models that you can use to study plane stress, plane strain, and generalized plane strain in your solid mechanics problems.
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.
How to Use the Load Plots in Structural Analyses
You can use the load plots available in the COMSOL® software to get the best possible visualization of the loads acting on your structural mechanics models in various situations.
Frequency Response of Mechanical Systems
Read this blog post for a detailed look at damped mechanical systems, a guide to setting up frequency-response analyses in COMSOL®, and a discussion of how to interpret your results.
Introduction to Numerical Integration and Gauss Points
In this comprehensive blog post, we go over the theory behind numerical integration, Gaussian quadrature, Gauss points, weak contributions, and much more.
