Xa iityhubhu zentsimbi ezingenamthungo zitsalwa ngokubanda, iziphene zetyhubhu ezishushu eziqengqelekayo ezifana neentanda okanye ubukho bomzobo ochanekileyo ophezulu wokuzoba itanki yepetroli yenziwa emva kokuba uqhekeko lwenzekile ekhosini, phantse akukho deformation yeplastiki eyenzekayo, ngokuqhelekileyo i-brittle fracture. I-Brittle fracture ibangelwa izizathu ezahlukeneyo. Njenge: umda weenkozo unciphisa, kungakhathaliseki ukuba yintoni eyomelele ngaphezu kwamandla e-matrix okanye ibuthathaka, zonke zibangela ukuqhekeka; ulwahlulo kwi-inclusions yomda wengqolowa yizizathu ezaphukileyo; Ngaphaya koko, nangaphantsi kakhulu kunomda wesivuno somnqamlezo phantsi kwemithwalo eguquguqukayo, nako kunokubangela ukudinwa ukwaphuka kwenzeke.

Ngokubanzi, iipropathi zomatshini zamacandelo e-hydraulic (pneumatic) asetyenziswa ekuyilweni, izinto ezithathwa njenge-homogeneous, eziqhubekayo, isotropic, ngokwale ndlela yokuhlalutya kuthathwa njengoyilo olukhuselekileyo, ngamanye amaxesha iingozi ziya kwenzeka ukuphuka. Uphononongo lufumene ukuba uxinzelelo oluphantsi lwe-brittle fracture process lwenzeka kumandla aphezulu we-metallic materials, umbutho wezinto eziphathekayo ukude kwi-homogeneous, isotropic. Imibutho ineentanda, kuya kubakho ukufakwa, i-porosity kunye nezinye iziphene ezinokubonwa njenge-microcracks yezinto. Ukongeza, i-brittle fracture kunye nelungu lobushushu obufanelekileyo. Xa abantu ngophando bafumanisa ukuba xa iqondo lobushushu lehla ngaphantsi kweqondo lobushushu elithile, izinto ziya kuguqulwa ibe yimeko brittle, impembelelo efunxa amandla yehla, into eyaziwa ngokuba brittleness ebandayo, ngoko uyilo kodwa ngokutsho ilungu lobushushu esebenzayo khetha. kunye nobushushu obufanelekileyo benguqu ebandayo yento.
