Ukutywina okuphambili
Xa ulwelo oluhambayo, irhasi, uthuli kunye nolunye udaba kwimibhobho kugxininiswa, uxinzelelo lomlomo wokutywina oqhotyoshelwe kumphezulu womzimba wombhobho nawo uyomelezwa. Ngoncedo lwesakhiwo sefowuni, ayisiyiyo nje kuphela ukuvuza kwendlela kumbhobho othintelweyo, kodwa kunye nokusebenza ngokutywina kombhobho kuqinisekisiwe.
Ngexesha loxinzelelo, ngokomgaqo we-basiger we-hydrodynamics, kwimeko yokutywina, kukho uxinzelelo oluqhelekileyo olulinganayo noxinzelelo lwangaphakathi kuyo yonke indawo yokunxibelelana nophakathi, ngoko ke umlomo osemazantsi womsesane wokutywina ucinezelwe, imilebe icinezelwe i-axially, umphezulu woqhakamshelwano phakathi komlomo wokutywina kunye nombhobho wandiswa, kwaye uxinzelelo loqhakamshelwano lwandisiwe, ukwenzela ukufezekisa isiphumo sokutywina, njengoko kubonisiwe kwi Umzobo1.
Ngaphantsi kwesenzo soxinzelelo, umphezulu wokutywina kunye nemibhobho zihambelana kakhulu, ezinokuqinisekisa ngokufanelekileyo ukutywina. Ingabonakala kwimeko yokusebenza eyiyo ukuba isangqa sokutywina sisitywina esimileyo, kwaye iimeko zokusebenza ezinobuzaza ikakhulu kukungcangcazela okuncinci kunye nokushukuma kwempembelelo. Ngokutsho kweempawu zohlobo lwe-Y, itywina lesitywina linokuthwala itywina elinamandla angaphezu kwe-20MPa.
Igobolondo lolona xinzelelo luphambili lwenxalenye yesinxibelelanisi semibhobho, echaphazela ngokuthe ngqo ukhuseleko kunye nokuthembeka kosetyenziso olululo. Kuyimfuneko ukwenza uhlalutyo lobunzulu boomatshini bokuchonga ukumisela ukuba ingaba amandla oxinzelelo ngalunye phantsi koxinzelelo lokusebenza olulinganisiweyo ahlangabezana neemfuno zokusetyenziswa, fumana indawo yoxinzelelo, kunye nokwenza uguquko oluhambelanayo kunye nophuculo, ukuqinisekisa ukhuseleko nokuthembeka.
Ukomelela kwegobolondo kunxulunyaniswa nobunzima be-tensile, i-ductility, ubukhulu kunye nezinye izinto ezisetyenzisiweyo. Ukubotshwa kweebholithi ezisetyenzisiweyo kuya kubangela ukuvela kweqokobhe elithile. Ukongeza, imilebe yegobolondo iya kukhubazeka phantsi koxinzelelo. Ezi zinto zizinto ezichaphazela uxinzelelo kuxinzelelo, ukhuseleko kunye nokuthembeka kweqokobhe.
Imodeli yento eqingqiweyo yeqokobhe isekiwe, njengoko kubonisiwe kwi Umzobo2
Ukuxhathisa okuphambili.
Ezi ziphelo zibini zendibaniselwano zamkela ubume bokubamba okunobuchule. Emva kofakelo, i-clasp kuhlobo lwezinyo esisigxina ilume ngokuqinileyo iluma umphezulu wombhobho. Xa uxinzelelo ngaphakathi kombhobho lonyuka okanye amandla e-axial enyuka ngenxa yempembelelo yamandla angaphandle, i-clasp iya kuqinisa umzimba wombhobho
