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 >>
Selecting First Gear: Investigating a Classic Car Gearshift Mechanism
Follow along as we perform a multibody dynamics analysis of the gearshift mechanism in a classic car. Read to hit the road?
