Is brittle fracture of steel or steel structures the destruction of steel by sudden rupture at stresses below the tensile or yield strength of the steel?
Steel structures, especially welded structures, often have crack-like defects due to the quality and construction of the steel, processing and manufacturing, and welding.Most of the brittle fracture is due to the development of these defects so that the crack instability and expansion occurred, when the crack slowly expanded to a certain extent, the fracture that is to expand at a very high rate, brittle fracture before the sudden occurrence of any warning, the destruction.
