Spiral simbi pombi inotonhora inodhonzwa, inopisa yakakungurutswa chubhu kuremara, senge makatsemuka kana spiral simbi yakakwirira-chaiyo inotonhora inodhonzwa pombi mushure metangi, mukati mekutsemuka, kunenge pasina deformation yepurasitiki inoitika, iri brittle kuputsika. Brittle fracture inokonzerwa nezvikonzero zvakasiyana-siyana. Zvakadai se: the precipitate pamiganhu yezviyo, pasinei nekusimba kwavo kwakasimba kana kuderera kudarika simba rematrix, zvose zvinokonzera kuputika. Kubatanidzwa pakuparadzaniswa kwemuganhu wezviyo ndicho chikonzero chechinetso. Pamusoro pezvo, kunyangwe pazasi pemuganho wegoho rekuchinjanisa mutoro, zvinogona zvakare kutungamira kune kuneta kutyoka.

Brittle fracture pa low stress high simba metallic materials inoitika panguva yesangano iri kure nehomogeneous, isotropic material. Sangano richava nekuputika, pachava neakadaro inclusions, porosity defects, izvi zvinokanganisa zvinogona kuonekwa muzvinhu zve microcracks. Mukuwedzera, iyo brittle fracture inoenderana nechikamu chetembiricha kushandiswa. Vanhu kuburikidza netsvagiridzo vakawana kuti kana tembiricha yadonha pazasi peimwe tembiricha, zvinhu zvacho zvinoshandurwa kuita brittle mamiriro, zvichideredza maitiro ekunyudza basa, chiitiko chinozivikanwa se brittle.
