Concrete Beam with Reinforcement Bars
Model ID: 10440
Concrete structures almost always contain reinforcements in the shape of steel bars ("rebars"). In COMSOL, individual rebars can be modeled by adding a Truss interface to the Solid interface used for the concrete. The solid mesh for the concrete and the rebar mesh can be independent, since the displacements are mapped from within the solids onto the rebar at a certain position.
