Ipayipi lensimbi elivunguzayo elidonswa ukubanda, ishubhu elishisayo eligoqiwe amaphutha, njengokuqhekeka noma insimbi evunguzayo, ipayipi elidonsa ngokunemba eliphakeme elibandayo ngemuva kwethangi, phakathi nokuphuka, cishe akukho ukuwohloka kwepulasitiki okwenzekayo, ukuphuka kwe-brittle.I-Brittle fracture ibangelwa izizathu ezihlukahlukene.Okufana nokuthi: imvula emingceleni yokusanhlamvu, kungakhathaliseki ukuthi inamandla kangakanani noma ibuthakathaka kunamandla e-matrix, yonke imbangela yokuqhekeka.Ukufakwa ekuhlukaniseni umngcele wokusanhlamvu kuyimbangela yenkinga.Ngaphezu kwalokho, ngisho nangaphansi kakhulu komkhawulo wesivuno womthwalo oshintshanayo, kungaholela nasekuqhekekeni kokukhathala.

I-Brittle fracture ekucindezelekeni okuphansi kwamandla aphezulu izinto zensimbi zenzeka ngesikhathi senhlangano kude ne-homogeneous, i-isotropic material.Inhlangano izoba nemifantu, kuzoba khona okufana nokufaka, ukukhubazeka kwe-porosity, lezi ziphambeko zingabukwa ezintweni ze-microcracks.Ngaphezu kwalokho, ukusetshenziswa kwe-brittle fracture kuhlobene nezinga lokushisa.Abantu ngocwaningo bathole ukuthi lapho izinga lokushisa lehla ngaphansi kwezinga lokushisa elithile, impahla izoguqulwa ibe yizimo eziphukayo, inciphise umsebenzi wayo wokumunca umthelela, into eyaziwa ngokuthi yi-brittle.
