Iintlobo deformation

Deformation - le icala okanye kukwaphula isibopho phakathi atom. Kubonakala ukuba ngenxa imikhosi impembelelo ecaleni: iqondo lobushushu, uxinzelelo, umthwalo ethile, Imagnethi yomhlaba okanye zombane. Iindidi eziphambili deformation - ingathityazwa lakho. deformation ingathityazwa physics ekuthiwa deformation ilastiki, ithetha ukuba imixokelelwane phakathi athom ukungathobeli kancinane kunye nesidima nesakhiwo bangaphazamiseki. Ukuba isakhiwo eso kuthiwa izinto elastic. deformation vuhlayiseki physics kuthiwa deformation zeplastiki kwaye ukwaphulwa neentambo kwi athom, kwaye ngenxa yoko, ukuthembeka isakhiwo. Izinto nalo mhlaba ngokuba plasticity.

Ukophulwa ubuhlobo atom - ukuba akusoloko into embi. Umzekelo, damping (ucimayo oscillations) Izinto kufuneka plasticity. Kuyimfuneko ukuba ukuguqula amandla ifuthe ibe amandla deformation. Ezi ndidi zilandelayo deformation of eziqinileyo: ukugotywa, ukungakhululeki / ucinezelo, torsion uchebe. Kuxhomekeka kuhlobo imikhosi ebambeleyo ekhankanyiweyo umzimba eziqinileyo, kusenokubakho ombane efanelekileyo. Ezi ntshikilelo nibizwayo uhlobo amandla. Umzekelo, torsion ntshikilelo, ntshikilelo compressive, uxinezeleko ayeguqa, njl Ethetha ubugqwetha, ngokufuthi ngokungagqibekanga kuthetha deformation of eziqinileyo, njengoko isakhiwo ukutshintsha lolona zabo.

Enyanisweni, zonke iintlobo deformation - ngesiphumo yempembelelo ombane eyenziwe amandla asebenzayo. Xa uhlobo olunyulu deformation ezinqabileyo. Njengoko umthetho, uhlobo iyonke - sisiphumo ezahlukeneyo ntshikilelo. Ngenxa yoko, bonke akhokelela Ngeentlobo ezimbini eziphambili - zolule / ucutheko ukugoba.

Ngokomzimba deformation - isiphumo nto ichazwa ngendlela ubunjani kunye neenkcukacha zamanani. Nangokobungakanani le nto ichazwa njenge lixabiso lenani. Ngokomgangatho - ubonisa uphawu (ulwalathiso ngongoma, ezifana ngokwaphulwa, umda ombane ...). ngaphambili deformation kunokwenzeka libalwa izibalo amandla xa eyila nasiphi na isixhobo okanye izixhobo.

Ngokuqhelekileyo, iziphumo umthwalo-deformation eboniswe kwifom igrafu - imizobo ntshikilelo. Ubume kule grafu: cebo ibalwa isicelo imithwalo, iintlobo kunye iintlobo xi deformation. distribution umthwalo sinika ukuqonda yohlobo kulayishwa na isixhobo okanye element deformation. uhlobo Iziphumo - kwempixano, ucinezelo, ayeguqa, ukujiwuza - umlinganiselo ngeeyunithi neefoni womlinganiselo (mm, cm, m) okanye umlinganiselo emboxo (degrees, kwilayini eziqala embindini). Basic umsebenzi ukubala - ukufumanisa ubunzima umda kunye ntshikilelo siphephe ukusilela intsebenzo - discontinuity uchebe ngokwaphulwa njalo njalo. Okubaluleke ngokulinganayo uhlobo yoxinezeleko lixabiso lenani njengoko Kukho ingqikelelo ukudinwa deformation.

Ukukhathala deformation - inkqubo yokutshintsha isimo ngenxa imithwalo ezininzi. Baya ekugqibeleni kumaxhala non-ebaluleke kakhulu (ukugxojwa rhoqo abaselula baloo iibhondi interatomic) ukuphuhlisa zibe nemiphumela emibi. Lo mbono kuthiwa fatigue ababeyiqwebile ilawulwa parameter onjalo (of iimpawu ebonakalayo le material), njengoko amandla kudinwa.

Ukuze ingqalelo ifuthe iintlobo ezahlukeneyo ubunzima nokusebenza kunye nezixhobo, kuqhuba iimvavanyo ngumhlaba iisampuli eziphathekayo. Ngokwamava lokufumana zonke iimpawu amandla ukuze izinto nganye, neziye zithi ke ngoko zibe amaxabiso ezivunyiweyo. Xa xesha ubuchwepheshe be-computer, azihlole ikhutshwa phandle kwi ekupheleni phezulu-PC. Ke zonke iipropati enye into sinokukufunda kuphela iimvavanyo wentsimi. Sele ngokubekwa zonke iimpawu kunye iipropati imodeli ukubala, prochnist ifumana imodeli lomzobo (maxa wambi Dynamics ukusebenza) zonke yoxinezeleko yobunzima.

Kubunjineli, le ubalo sele babekwa iprogram 3D-design. ie lowo wengcibi yokuluka ezisebenza 3D-umfuziselo zonke izinto, nganye reduced imodeli ebandleni. Ngokufaka umthwalo kwi imodyuli olwahlukileyo lwenkqubo, lowo wengcibi yokuluka uyithathaphi umfanekiso womthamo lwe yohlobo xi ubunzima zonke iintlobo.
