chrono::fea::ChBeamSectionCosseratEasyCircular 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 circular centered beam. This section automatically creates, initializes and embeds, at construction, these models:

#include <ChBeamSectionCosserat.h>
