Effect of sheet electron beam irradiation on hardness, fracture diameter, fracture load and fracture toughness were studied for silica glass surface. Although the hardness value was not changed by the irradiation, it improved the brittleness, strength and fracture toughness of ultra-thin sheet of glass surface. The improvements can be explained by stress relaxation induced by increase in dangling bonds density.
