A reinforced concrete slab can be strengthened by adhering carbon fiber sheets to the tension side. This is a common practice in concrete structure reinforcement (as shown in Fig.1) Fig.1. Carbon fiber reinforcement. In this problem, the reinforced concrete slab is simply supported. A carbon fiber sheet is attached to the lower surface of the … Continue reading Elastic-plastic analysis of a reinforced concrete slab strengthened by a carbon fiber sheet

The stress-strain curve of rubber material stiffened by carbon fiber
Fig.1. Illustration of the discretization and BCs A 2D model is created. Plane elements and beam elements are used to discretize rubber material and carbon fiber, respectively. To ensure that rubber and carbon fiber deform together (no slipping), plane elements and beam elements share common nodes. A concentrated force (the red arrow in Fig.1) is … Continue reading The stress-strain curve of rubber material stiffened by carbon fiber
