CFRP is currently one of the most widely applied Strengthened materials.
Separate model is treated steel bars and reinforced concrete materials as different elements respectively, thus the concrete materials and steel bars are all divided into small enough elements and connection elements are be used to simulate bond and slip between steel bars and concrete.
Integral models are made the distributions of steel bars among in entire elements and regarded FEM elements as continuous homogeneous materials.
