There is practically no disturbance of the stress at a distance equal to the crack diameter.
In the region of sharp cracks, narrow stress distortion regions are observed; they form an angle of 30–35° with the crack plane.
During the period of rupture of transparent bodies by a laser beam the tangential stresses are insignificant, being above one order smaller than the ultimate strength of the material.
