Umkhawulo amandla materials - kuyini?

izakhiwo Mechanical we metal noma ingxubevange ezifana ubulukhuni, ductility, ukumelana ukusonteka, amandla eqine noma ukuhuzuka ukumelana, - nenqubo esiyinhloko kukhethwa indaba.

Noma yimuphi metal (kanye ukhuni noma plastic), okuyinto ngaphansi kwethonya yimuphi umthwalo, akakwazi ngibavivinye phakade. Deformation kanye zokugwema ukuphuka ezenzeka ngaphansi kwazo zonke izimo ezingezinhle nemibandela yokusebenza ehlukile kufanele kubhekwe uma ngayinye. Isibonelo, ukungeza nokubunjwa amakhemikhali ingxubevange ye-elementi, indlela kucutshungulwa isizinda, khona noma ukungabi khona okuqinile-chrome enamathela ukuvumela ezahlukene show ngokwabo ukuba ukwaziswa okufanayo e ezahlukene ukusebenza izindlela.

amandla eqine izinto ngalinye wazimisela empirically futhi ukuhlaziya eziyinkimbinkimbi zezibalo nokuhlolwa egunjini lokucwaninga esibhedlela. Ukusebenzisa izindlela ezihlukahlukene ingafinyelela imiphumela yokuhlolwa sinembe kakhulu.

Idatha etholwe ifinyeziwe iziqondiso iyunifomu - kude, OST Izikhombo wajabulela lapho kubalwa kanye kukhethwa indaba oyifunayo. I ukumelana izinsimbi kanye Alloys zonke deformations kungenzeka nokubhujiswa kunqunywa isici mechanical ezifana amandla eqine ngensimbi noma insimbi inkatho, esiyinhlanganisela, ukhuni noma plastic, kuthinta nokwethenjelwa inkonzo impilo umkhiqizo.

Kukhethwa kwesokudla impahla kanye nokusebenzisa kwayo okunengqondo kukhona isiqinisekiso abazalwa kwezomnotho kulingane ukuphepha ukuqina isakhiwo. Ngo umkhakha yesimanje, zonke izinto kufanele kube nezakhi ezihlukene elilungile. amandla eqine, ukukhathala noma ukucindezeleka, ukumelana zesikhashana ukuba eguqa noma kokucindezelwa, torsion noma ukungezwani akufanele ezidlula izimfuneko osekuyisikhathi namazinga. a ukusonteka okuncane kuphela kuvumelekile izibalo.

Uma umthelela umthwalo idlule umkhawulo avumelekile amandla, lapho kufika umzuzu nolokubhujiswa izingxenye, imishini noma izakhiwo. Ngakho ekukhetheni okubi of impahla kunomthelela izindleko hhayi kuphela ezengeziwe for ukukhanda noma ukushintsha izingxenye noma indlela kodwa futhi ukubhujiswa okuphelele kwalelizwe isakhiwo sonke.

Kusukela ukusebenza isikhathi ukumelana mechanical incike ukuthembeka design, ubude inkonzo izingxenye, imishini kanye nezinto zokusebenza. Ngokwesibonelo, amandla eqine ensimbi grade 45 e ukungezwani noma kokucindezelwa, torsion noma eguqa has ukusebenza elilungile. Kuyinto lokhu uhlobo steel uvame esetshenziswa ukwenziwa izingxenye netindlela ezidinga okusezingeni eliphezulu amandla izici.

Steel nensimbi esetshenziswa ekwakheni, azikakutholi engena esikhundleni ehloniphekile. Ngenxa izindlela ezintsha ukuze zamagama lezi zinsimbi nokusetshenziswa kwawo lokucubungula yesimanje lezi zinhlobo zezindwangu kuba unyaka ngamunye. Ukuthembeka, ukuqina kanye namandla eqine elilungile - kokusebenza kakhulu.
