Modeling Thermal Fatigue in Nonlinear Materials
2 challenges when simulating fatigue in nonlinear materials: 1.) Correctly representing the material behavior and 2.) finding a fatigue model that captures the life-controlling mechanism.
Natural Frequencies of Immersed Beams
A guest blogger from Veryst Engineering demonstrates the modeling of a cantilever beam immersed in a fluid to study its natural frequencies. Read it here >>
What Kinds of FSI Problems Can COMSOL Multiphysics Solve?
We discuss the various techniques for modeling fluid–structure interaction (FSI) in the COMSOL® software, as well as highlight the add-on modules you need for these various types of analyses.
Modeling the Hydrostatic Pressure of a Fluid in a Deformable Container
Picture a water balloon being compressed at the center. As you squeeze the balloon, the locations of the highest point and depth of fluid change, altering the hydrostatic pressure distribution.
Computing Stiffness of Linear Elastic Structures: Part 2
Learn how to compute the stiffness of linear elastic structures in 2D and 3D with COMSOL Multiphysics® by implementing the Poisson effect. Part 2 of a 2-part series on computing stiffnesses.
Computing Stiffness of Linear Elastic Structures: Part 1
Learn how to compute the stiffness of linear elastic structures in 1D and 2D by implementing the Timoshenko beam theory in COMSOL Multiphysics®. Part 1 of a 2-part series on computing stiffness.
Using Cyclic Symmetry to Reduce Computation Time
Cyclic symmetry can be more complex for rotationally geometries than it can for axially symmetric geometries. Learn how to implement this feature to cut down on computational memory.
Defining Curvilinear Coordinates for Anisotropic Materials
Consider a carbon-fiber-reinforced polymer with woven fibers embedded in an epoxy matrix. How can you express the anisotropy by referring to the well-known Cartesian coordinate system?
