A master’s thesis in the College of Engineering at the University of Basrah discussing  (Analysis of crack growth in composite materials using the extended finite element theory)
The thesis presented by student Maha Sabah Kahyoush dealt with the use of different composite panels based on the direction of the angles of the fibers. The stress intensity factor and the shape factor were calculated for different fiber angle directions, different crack lengths and different crack locations for the same plate dimensions.
All for the same loading conditions, using the extended finite element theory. The plate is made of carbon and epoxy composite plate with five layers with the same fiber angles for each sample.
The simulation of crack growth in the structure of composite plates was also studied 5 layers with the same fiber angles per
A sample, in addition to the study of crack growth for some plates with 4 and 3 layers at different angles,
This thesis aims to analyze crack growth in composite materials using finite element theory
The thesis concluded that the stress factor increases significantly when the direction angle of the fibers increases, while
The form factor is reduced, and the result also shows that the incision does not grow with the original incision direction; Instead, it spreads
The slit along with the direction angle of the fibers.
