Brittle fracture under repeated high stresses
AbstractExperimental evidence of brittle fracture in cold press-braked square tube members is shown in this paper. The brittle fracture was preceded by fibrous cracks starting at the toes of the butt weld of the press-braked member connected to a diaphragm under reversals of bending moment beyond the elastic limit. To find out the causes of the brittle fracture, mechanical properties in the press-braked corner undergoing plastic strain and ageing were investigated. Sizeable decreases in ductile elongation capability and considerable reductions in notch toughness in the press-braked corner were observed.
