This paper experimentally investigates the effect of crack size on the stresses in pipes. Tensile test specimens with and without cracks were tested in universal testing machine. The load and the displacement were monitored during testing. The results show that the strength of the pipe was decreased w.r.t crack size with a power trend. The elongation until failure also shows a similar trend. The failure of the specimens with cracks occurs at the crack position.
