Fracture Failure Modes in Fiber-Reinforced Polymer Systems Used for Strengthening Existing Structures

Fracture Failure Modes in Fiber-Reinforced Polymer Systems Used for Strengthening Existing Structures

The development of promising new high-performance materials, such as composite materials made of fibers in a polymeric resin (fiber-reinforced polymer, or FRP), has transformed the structural rehabilitation and upgrade industry for buildings and infrastructure. Conventional materials and constructio...
