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?
Buckling, When Structures Suddenly Collapse
The easiest way to approach a buckling problem — like a bridge collapse or crushed soda can — is by performing a linearized buckling analysis. See how to do so in COMSOL Multiphysics® here >>
