chrono::fea::ChBeamSectionCosseratEasyRectangular Class Reference
Description
A simple specialization of ChBeamSectionCosserat if you do not need to define its separate models for elasticity, plasticity, damping and inertia.
Good if you just need the simplest model for a rectangular centered beam. This section automatically creates, initializes and embeds, at construction, these models:
- elasticity: ChElasticityCosseratSimple
- inertia: ChInertiaCosseratSimple
- damping: none - you can add it later
- plasticity: none
