🤖 Machine Learning-Assisted Analysis of Fracture Energy in Externally Bonded Reinforcement for Groove Bond Strength Prediction
🏗️ Introduction to Structural Strength Enhancement Modern civil engineering continuously seeks innovative ways to enhance the durability and strength of aging structures. One such method is Externally Bonded Reinforcement (EBR) , where advanced materials like fiber-reinforced polymers are bonded to structural elements to improve load-bearing capacity. However, the efficiency of this reinforcement highly depends on bond strength , especially in grooved surfaces where adhesion plays a critical role. Understanding fracture energy and predicting groove bond behavior has become essential for designing reliable reinforcement systems. ✨ 🔬 Fracture Energy and Bond Behavior Fracture energy refers to the energy required to propagate a crack in a material. In reinforced structures, cracks may occur between the substrate and the bonded reinforcement layer. By studying fracture energy, engineers can better understand how cracks initiate, grow, and ultimately affect the bond performance. G...
