DYNAMIC STRESS DISTRIBUTION AROUND THE TIP OF A RUNNING CRACK

The stress distribution was calculated around the tip of a crack running at constant speed in a brittle material. The stresses obtained were written as the sum of the associated static solution and the wave-effect terms. The results clearly reduce to the associated static solutions if the crack speed tends to zero. They also reduce to the crack- plane stresses if the vertical spatial variable y vanishes. Near the tip of the crack, the dynamic stress-intensity factor for the circumferential stress was written as the product of the associated static stress-intensity factor and the dynamic correction factor.
