Umbhobho wentsimbi ojikelezayo uyabanda, iziphene zetyhubhu eshushu eziqengqelekayo, ezinje ngeentanda okanye intsimbi ejikelezayo echanekileyo, umbhobho otsalwa ngokuchaneka kakhulu emva kwetanki, ngexesha lokwaphuka, phantse akukho luguquko lweplastiki lwenzekayo, kukuqhekeka okunokonakala.I-Brittle fracture ibangelwa izizathu ezahlukeneyo.Njenge: i-precipitate kwimida yengqolowa, kungakhathaliseki ukuba ubuninzi babo bunamandla okanye bubuthathaka kunamandla e-matrix, yonke into ebangela ukuqhekeka.Ukufakwa kwi-container boundary yahlulwa ngunobangela wengxaki.Ukongeza, nangaphantsi komda wesivuno somthwalo otshintshanayo, kunokukhokelela ekudinweni ukwaphuka.

I-Brittle fracture kuxinzelelo oluphantsi amandla aphezulu izixhobo zentsimbi zenzeka ngexesha lombutho kude ne-homogeneous, isotropic material.Umbutho uya kuba nokuqhekeka, kuya kubakho okufana nokubandakanywa, iziphene ze-porosity, ezi ziphene zinokujongwa kwizinto eziphathekayo ze-microcracks.Ukongeza, i-brittle fracture inxulumene nokusetyenziswa kweqondo lobushushu.Abantu ngophando bafumanisa ukuba xa ubushushu behla ngaphantsi kobushushu obuthile, izinto eziphathekayo ziya kuguqulwa zibe ziimeko ezinqabileyo, ukunciphisa umsebenzi wayo wokufunxa impembelelo, into eyaziwa ngokuba yi-brittle.
