Determination of Plastic Fracture Deformation of Steel Bueno, R. Department of Mechanic and Structures. University of Seville, Spain Avenida Reina Mercedes, 2. 41012 Seville, Spain (email: [email protected]) Abstract This study develops a new method for determining the plastic fracture deformation of steel, using for this purpose the simple standardized tensile test on a cylindrical test specimen and evaluating the sectional deformation in the necking after rupture by means of an optical profile projector. This procedure eliminates the disadvantages of the current method employed to determine elongation at fracture ( A5d or A10d ) , steel mechanical property required in the structural concrete codes of many countries ( Germany , France , Spain ,etc ) and presents immediate applications in the field of Science and Engineering of Materials and Quality Control of Metals. Keywords: true strain, elongation, ductility, necking, uniaxial tension test 293
