From the graph a 1040 st33l that has been cold worked approximately 20% has a ductility of. Cw% = (1 - (df/d0)2) x 100 d0 = df / (1 - cw%/100)1/2 df= Tensile strength (psi) = 500 x brinell hardness (bhn) Brinell hardness (bhn) = tensile strength (psi) / 500. Y1 - y2 = 0 - 0 + ky x (d1. 1/2) ky =( y1 - y2 ) / (d1. Critical = k1c /(y x ( x a)1/2) = 2016-10-19: a cylindrical bar of cold-worked 1040 steel has a ductility of 13% and a diameter of. The data collected during the experiments is included in the table below.
