kei hea: e = te whakaroa iti i roto i te 2 inihi (50 mm), %, porotaka ki te 0.5% tata, A = te horahanga whitinga o te tauira whakamatautau riipoi, in.2 (mm2), i runga i te diameter o waho kua tohua, i te whakaingoa ranei i tohua te diameter o waho, te whanui tauira whakaingoa ranei me te matotoru pakitara kua tohua, kua whakaawhiwhia ki te 0.01 in.2 tata (1 mm2) . (Mehemea he rite, nui ake ranei te horahanga i te 0.75 in.2 (500 mm2), katahi ka whakamahia te uara 0.75 in.2 (500 mm2). U = te kaha tensile kua tohua, psi (MPa). |
Hei taapiri atu ki te whakarite i te hanganga matū me nga taonga miihini, ka mahia nga whakamatautau hydrostatic takitahi, ka mahia nga whakamatautau mura me te papatahi. . I tua atu, kei reira etahi whakaritenga mo te microstructure, te rahi o te witi, me te paparanga decarburization o te paipa maitai oti.
