Answer
Igice gihoraho (disformasiyo ya plastike) kibaho mugihe imihangayiko yo hejuru yumuraba irenze imbaraga zumusaruro wibikoresho $ \ sigma_y $. Niba ibi bibaye ku bushyuhe bwinshi, birashoboka bitewe n '' kuruhuka '. Nubwo imihangayiko yabazwe yari munsi ya $ \ sigma_y $ mubushyuhe bwicyumba, imbaraga zumusaruro wibikoresho nka 17-7PH bigabanuka uko ubushyuhe bwiyongera. Ikindi gishoboka ni 'kurenza-compression' kugeza murwego rukomeye aho guhangayikishwa nukuri $ \ sigma = \ frac {48 \ cdot E \ cdot t \ cdot f} {\ u03C0 ^ 2 \ cdot D_m ^ 2} $ irenze imipaka ya elastique. Kugira ngo iki kibazo gikosorwe, isoko igomba kuba 'igenamigambi' (igabanijwe kugeza ku burebure bukomeye mu gihe cyo gukora) kugira ngo itere imbaraga zo kwikuramo ibisigisigi, cyangwa ibikoresho bigomba kuzamurwa bikagera kuri superalloy nka Nimonic 90.
