How to Model Adhesion and Decohesion in COMSOL Multiphysics
Did you know you can simulate objects that stick together once they come in contact (adhesion) as well as those that pull apart (decohesion), including full cohesive-zone modeling?
How to Make Boundary Conditions Conditional in Your Simulation
In some modeling scenarios, you may want to apply a boundary condition to only part of the geometrical boundary or only under certain conditions. Learn how to do so here.
Modeling the Dynamics of a Gyroscope
Gyroscopes and spinning tops aren’t just old-fashioned toys. Using models of these 2 structures, we illustrate the remarkable properties of rotating bodies.
What Is Geometric Nonlinearity?
If you perform structural mechanics analyses, then you have most likely encountered the concept of geometric nonlinearity. But what exactly does geometric nonlinearity mean?
Modeling Linear Elastic Materials – How Difficult Can It Be?
Get an intro to the theory and application of the linear elastic material model, isotropy/anisotropy, allowable values for material data, incompressibility, and geometric nonlinearity.
Singularities in Finite Element Models: Dealing with Red Spots
Seeing red? Explore common causes of singularities in your finite element models, as well as when and how to remove them and how to interpret your simulation results.
Part 2: Obtaining Material Data for Structural Mechanics from Measurements
Learn how to use nonlinear elastic and elastoplastic materials, as well as a method for using your measured data directly in COMSOL Multiphysics®. Part 2 of a series on hyperelastic materials.
