Abstract :
In this paper the effect of composite hoop-wrapped on stress intensity factor
for semi-elliptical external crack which located in spherical pressure vessel,
were investigated through the Finite Element Analysis. In order to find the
effect of some parameters such as composite thickness and width, internal
pressure and crack geometry, comparisons between different cases were done
and discussed in detail. The result show that repairing crack with composite
hoop-wrapped, can significantly reduce the stress intensity factor along the
crack front.
