Reinforced Concrete Beam (COMSOL Multiphysics )

This example demonstrates how to incorporate steel reinforcement that is much smaller than the geometrical dimensions of the concrete structure.
Instead of a 3D solid, the steel reinforcements are modelled using the truss interface. Modeling them as solids would require a large number of tiny elements and result in an unduly long solution time.

Four different variants of modeling are compared:
Elastic beam without rebars
Elastic beam with elastoplastic rebars
Ottosen model for the concrete and elastoplastic rebars
Mazars damage model for the concrete and elastoplastic rebars
