Note that many of the examples featured here can also be accessed via the Application Libraries that are built into the COMSOL Multiphysics® software and available from the File menu.

Concrete Beam With Reinforcement Bars

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.

Isotropic Compression With Cam-Clay Material Model

Isotropic compression is a common exercise in soil testing. The modified Cam-Clay model describes the relation between the void ratio and the logarithm of the pressure. In this example, a soil sample is placed inside cylinder 10 cm in diameter and 10 cm in height. Due to the symmetry, the model is solved in 2D axial symmetry. A boundary load produces isotropic compression conditions.

Flexible and Smooth Strip Footing on Stratum of Clay

A common verification model for geotechnical problems is of a shallow stratum layer of clay. In this model, a vertical load is applied to the clay strata top surface and the static response and collapse load are studied. The clay is modeled as an elastic-perfectly plastic material and the Mohr-Coulomb yield condition under plane strain conditions is used. The response is studied using an ...
