Girazi chinhu chakaoma uye chine brittle.Zvisinei, chero bedzi yakanyungudutswa pakupisa kwepamusoro uye nokukurumidza kukweverwa kuburikidza nemakomba maduku mumagetsi egirazi akanyatsonaka, zvinhu zvinoshanduka zvikuru.Zvakafanana girazi, nei girazi rakajairwa girazi rakaoma uye brittle, nepo girazi refibrous richichinjika uye rinochinjika?Izvi zvinonyatsotsanangurwa nemaitiro ejometri.
Fungidzira uchikotamisa tsvimbo (uchifunga kuti hapana kuputsika), uye zvikamu zvakasiyana-siyana zvetsvimbo zvichange zvakakanganiswa kusvika kune zvakasiyana-siyana, kunyanya, rutivi rwekunze rwakatambanudzwa, rutivi rwemukati rwakamanikidzwa, uye ukuru hweakisi hunenge husina kuchinja.Kana yakakotama pakona imwe chete, iyo yakatetepa kamuti, iyo kunze kwayo inotambanudzwa uye kushoma mukati inomanikidzwa.Mune mamwe mazwi, iyo yakatetepa, idiki dhigirii renzvimbo yekusimba kana compressive deformation yedhigirii rimwe chete rekukotama.Chero chipi zvacho chinogona kuita imwe dhigirii yekuenderera mberi deformation, kunyangwe girazi, asi brittle zvinhu zvinokwanisa kumirisana nekushomeka kwakanyanya pane ductile zvinhu.Kana iyo girazi faibha yakatetepa zvakakwana, kunyangwe dhigirii rakakura rekukotama rikaitika, dhigirii renzvimbo yekutemesa kana compressive deformation idiki kwazvo, iri mukati mekutakura kwezvinhu, saka haizoputsi.
