chrono::fea::ChBeamSectionEulerEasyRectangular Class Reference
Description
A simple specialization of ChBeamSectionEuler if you just need the simplest model for a rectangular centered beam, with uniform elasticity and uniform density.
This section automatically itializes at construction:
- elasticity as rectangular section
- inertia as rectangular section
- damping: none - you can set it later
