Abstract

To arrest the crack propagation in structures subjected to fatigue load, drilling a hole ahead the crack tip is one of the most common repair technique. Due to site restrictions and geometrical constraints drilling an adequate size crack stop hole may not be possible. In such situations, to strengthen the undersized crack stop hole a carbon reinforced fiber polymer (CFRP) is attached to the structure. In the present study the effect of combined action of crack stop hole and CFRP laminates under static tensile loading is studied by using finite element analysis and validated by experimental studies. The finite element analysis is carried out in ANSYS 12.0 software and experimental studies are carried by universal testing machine (UTM)in Structural engineering laboratory, IIT Hyderabad.
