Interfacial fracture analysis of adhesive-bonded joints Won-Seock Kim 1,a and Jung-Ju Lee2,b 1,2 Department of Mechanical Engineering, ME 3033, KAIST, Science Town, Daejeon, South Korea a goodman@kaist.ac.kr, bleejungju@kaist.ac.kr Keywords: Adhesive-bonding, Interfacial strength, fracture toughness.
The results show that interfacial fracture mechanics characterization of adhesion strength can be a practical engineering tool for predicting the load-bearing capacities of adhesive-bonded joints.
Aircraft, automobiles, and many types of civil infrastructure contain many adhesively bonded components that support various types of loads.
Although many engineers have used stress-based approaches, fracture mechanics characterization is regarded as providing a reliable tool for predicting the failure of bonded structures.

By using FEM method, the natural frequencies of the super-long steel and CFRP cables with possible engineering parameters have been comprehensively studied.
In practical engineering, these assumptions may cause great errors, and because the influence of sag on in-plane and out-plane frequencies is different, in-plane and out-plane vibration of cable have great difference.

FC, when appropriately engineered and cured, has excellent durability and resilience to climatic conditions including freeze-thaw cycles.
The lightweight characteristics and convenient positioning of this material make it well-suited for application in road building, bridge abutments, and several other civil engineering endeavours.
Adequately engineered and well-maintained FC constructions have a lifespan of 20-50 years or beyond.
