Description

Creates a reinforced matrix material. It combines a matrix material (e.g. concrete) and a reinforcement material (e.g. steel).

Usage

1. To create a new MaterialReinforced object do the following:
   • Click the Reinforced material (concrete) button or choose the Model → Materials → Reinforced material (concrete)‏‎ option from the menu.
2. To edit an existing MaterialReinforced object:
   • Double-click it in the Tree view.
3. Select the matrix material.
4. Optionally press the Edit button to edit its properties. The following material properties have to be defined: Young's modulus, Poisson's ratio, compressive strength and angle of friction.
5. Select the reinforcement material.
6. Optionally press the Edit button to edit its properties. A yield strength has to be defined.

Notes

• In the CalculiX solver settings, one has to set Material Nonlinearity to linear if FEM MaterialMechanicalNonlinear is not used.
• More information about this feature, and an example of its usage, can be found in Analysis of reinforced concrete with FEM.
• For a video tutorial (based on the FEM Tutorial) that uses this tool, watch: FEM MaterialReinforced tutorial.
