Ukurhweba kuxhaphake kakhulu ekukhuphuleni iintambo, ikakhulu ezisetyenziselwa ukunyuswa, ukutsala kunye noxinzelelo, njl.njl., kuba amandla okuqina okuphezulu afunyenweyo wonke umntu amkelwe kakuhle. Kodwa ngaba ukuqina kwentambo yocingo kufuneka kube yi-ductile?

Apha kulo mbandela kwaye sihlola ubukhulu becala, okokuqala ukuba yonke into iyanyuka, kodwa ukwandiswa kwegophe kuyahluka, apha sisathetha ngokwemigaqo yobuchwephesha yi-curve yoxinzelelo lwe-tensile. Njengesixhobo, kufuneka siqale siqinisekise ukuba asikwazi ukudlula uluhlu loxinzelelo lwe-elastic, olufuna ukurhweba kwethu ekuveliseni ixesha lokuthathela ingqalelo ixabiso loxinzelelo oluphezulu, kwaye emva koko siguqule ukugqithiswa kwenkqubo yokuvelisa kunye nolunye ulwazi.

Kakade ke, ukusetyenziswa kwentambo yentambo ayilokusetyenziswa okukodwa kudla ngokuba yinhlanganisela eninzi eyinkimbinkimbi yokusetyenziswa kwesakhiwo, esifuna ukuba sithathele ingqalelo uhlalutyo lomatshini lokuqina kokuqina kwempembelelo. Ngokuqinisekileyo, ukusuka kweli nqanaba ukukhwela kufuneka kube nenqanaba elithile le-ductility lingcono, kuba ekuphakanyisweni kwexesha ukuba amandla ngokukhawuleza angenazo iimpawu zokuxinana, ngoko ke ukukhwela ngokwayo kuya kuthwala umzuzu omkhulu woxinzelelo loxinzelelo, olu xinzelelo lwe-tensile kulula ukogqitha uxinezeleko lokugqibela olunokumelana nalo. Kwaye ukuba kukho iqondo elithile le-elastic tension, ngoko iya kudlala indima ethile ekuphakanyisweni kwe-buffer ukwenzela ukuba inokunciphisa kakhulu amathuba okuqhekeka kweentambo zocingo.
