Galasi ndi chinthu cholimba komanso chosasunthika.Komabe, malinga ngati amasungunuka pa kutentha kwakukulu ndipo kenako amakokedwa mofulumira kudzera m'mabowo ang'onoang'ono muzitsulo zabwino kwambiri zamagalasi, zinthuzo zimasinthasintha kwambiri.Momwemonso galasi, chifukwa chiyani galasi wamba ndi lolimba komanso losasunthika, pomwe galasi la fibrous limakhala losinthasintha komanso losinthasintha?Izi zimafotokozedwa bwino ndi mfundo za geometric.

Tangoganizani kupindika ndodo (poganiza kuti palibe kusweka), ndipo mbali zosiyanasiyana za ndodo zidzapunduka ku madigiri osiyanasiyana, makamaka, mbali yakunja imatambasulidwa, mbali yamkati imakanizidwa, ndipo kukula kwa olamulira sikungasinthe.Ikapindika pa ngodya yomweyi, ndodoyo imachepa thupi, kunja kumatambasulidwa pang'ono ndipo mkati mwake mumapanikizidwa.Mwa kuyankhula kwina, chocheperako, ndi chocheperako kuchuluka kwa kugwedezeka kwanuko kapena kupindika kopindika pamlingo womwewo wa kupinda.Chilichonse chimatha kupindika mosalekeza, ngakhale magalasi, koma zida zophulika zimatha kupirira mapindikidwe ocheperako kuposa zida zama ductile.Pamene ulusi wagalasi ndi woonda mokwanira, ngakhale kupindika kwakukulu kumachitika, mlingo wa kugwedezeka kwa m'deralo kapena compressive deformation ndi yaying'ono kwambiri, yomwe ili mkati mwazotengera zakuthupi, kotero sichidzasweka.

Zitha kuwoneka kuti kulimba ndi kuphulika kwa zida sizokwanira.Kuchita kwa zinthu sikungokhudzana ndi kapangidwe kake ka mkati ndi kapangidwe kake, komanso kukula kwake.Kuonjezera apo, zimagwirizananso ndi zinthu monga njira ya mphamvu.Mwachitsanzo, zinthu zambiri zimakhala ngati zamadzimadzi zomwe zimachitika pang'onopang'ono kunja, ndipo zimakhala ngati matupi okhwima pansi pa zochitika zakunja.Choncho, kugwiritsidwa ntchito kwapadera kapena zochitika zomwe zakhudzidwa ziyeneranso kuganiziridwa pofufuza zakuthupi.
