Finite element analysis of cracked steel plate

2 Finite element analysis of cracked steel plate 

When composite patching is provided to the cracked surface of a steel member, the composite patching provides deformation constraint to the cracked mouth. Rose (1982) carried out an analytical study estimating the reduction of the crack extension force when a cracked plate is repaired by reinforcing patches bonded on its faces. Rose pointed out that there are two main effects of the bonded reinforcing
