Kupsyinjika komwe kumapangidwa pamene chitsulo chazimitsidwa ndi zotsatira za superposition of thermal stress pa kuzizira ndi kupsinjika kwapangidwe panthawi ya kusintha kwa gawo. Kuthetsa kupsinjika ndizomwe zimayambitsa mapindikidwe ndi kusweka, ndipo kuyenera kuchepetsedwa kuti muchepetse kupsinjika.
pa nthawi yopanga ufa
Chikombolecho chiyenera kutenthedwa mpaka kutentha kwina kusanayambe kupanga, apo ayi, pamene chitsulo chosungunuka cha kutentha kwadzadza, nkhunguyo imakhala yozizira kwambiri, zomwe zimapangitsa kuti kutentha kwapakati ndi kunja kwa nkhungu kuchuluke, zomwe zimabweretsa kuwonjezeka kwa kutentha kwa mkati ndi kunja kwa nkhungu. kupsinjika kwamafuta, kusweka kapena kusweka pamwamba pa nkhungu.
Pakupanga, kutentha kwa nkhungu kumakwerabe. Kutentha kwa nkhungu kumatenthedwa, zimakhala zosavuta kupanga zomata, ndipo mbali zosuntha zimalephera kuwononga nkhungu pamwamba.
Dongosolo lowongolera kutentha kozizira liyenera kukhazikitsidwa kuti lisunge kutentha kwa nkhungu mkati mwamtundu wina.
