Tensile strength libhekisa kubuninzi boxinzelelo lokutsalwa (ukutsalwa) olunokumelana nezinto ngaphandle kokuphuka okanye ukusilela. Liyimpawu ebalulekileyo yoomatshini kwizinto, ingakumbi ezo zisetyenziswa kubunjineli nasekwakhiweni, njengoko libonisa ukuba zingakanani na amandla izinto ezinokumelana nawo ngaphambi kokuba ziguquke okanye ziqhekeke ngokusisigxina.

Amandla okutsalwa adla ngokulinganiswa kwiiyunithi zamandla kwindawo nganye, njengeeponti nge-intshi yesikwere (psi) okanye ii-megapascals (MPa). Uvavanyo lokufumanisa amandla okutsalwa lubandakanya ukunyusa kancinci kancinci amandla okutsalwa de aqhekeke. Ijika loxinzelelo oluvelayo libonelela ngolwazi oluxabisekileyo malunga nokuziphatha kwesixhobo phantsi koxinzelelo.

Kubalulekile ukuqaphela ukuba amandla okutsalwa yenye nje yeempawu ezininzi zoomatshini ezichaza ukusebenza kwento. Ezinye iimpawu, ezinje ngamandla okuvelisa, ukuguquguquka kwayo, kunye nokuthamba kwayo, nazo zidlala indima ebalulekileyo ekumiseleni indlela eza kuziphatha ngayo into phantsi kweemeko ezahlukeneyo zokulayisha.

Ukuqonda Amandla Okuxinana

Ukuqonda amandla okutyhafa kubandakanya ukuqonda iingcamango ezininzi ezibalulekileyo:

Inkcazo: Amandla okutsalwa yingcinezelo ephezulu enokunyamezeleka xa itsalwa okanye itsalwa ngaphambi kokuba iqhekeke okanye iqhekeke.

Umlinganiselo: Amandla okutsalwa adla ngokulinganiswa kwiiyunithi zamandla kwindawo nganye, njengeeponti nge-intshi yesikwere (psi) okanye ii-megapascals (MPa).

Uvavanyo: Amandla okutsalwa afunyanwa ngovavanyo lokutsalwa, apho isampulu yezinto ezisetyenzisiweyo itsalwa ngaphandle kusetyenziswa umatshini ide iqhekeke. Amandla asetyenzisiweyo kunye nobude obuhambelanayo besampulu ziyarekhodwa ukuze kuveliswe igophe loxinzelelo-loxinzelelo.

Ijika Loxinzelelo Loxinzelelo: Le curve ibonisa ubudlelwane phakathi koxinzelelo (amandla kwindawo nganye) kunye noxinzelelo (utshintsho kubude xa kuthelekiswa nobude bokuqala) ngexesha lovavanyo lokuxinana. Ngokwesiqhelo luquka iindawo ezahlukeneyo:

· Ummandla oNcibilikayo: Xa uxinzelelo luphantsi, izinto ziyaguquguquka ngendlela ethambileyo, oko kuthetha ukuba zibuyela kwimo yazo yokuqala xa uxinzelelo lususiwe.

· Indawo yokuvelisa: Uxinzelelo apho izinto ziqala khona ukubonakalisa ukuguquka kweplastiki, oko kuthetha ukuba ziguquka ngokusisigxina ngaphandle kokuqhekeka.

· Ummandla wePlastiki: Ngaphaya kwenqanaba lokuvelisa, izinto ziyaguquguquka njengeplastiki, ziqhubekeka ngakumbi ngenxa yoxinzelelo olukhulayo.

· Amandla Okuqina Okuphezulu (UTS): Uxinzelelo olukhulu olunokumelana nalo mbandela ngaphambi kokuba uqhekeke.

· Indawo Yokwaphuka: Uxinzelelo oluthi izinto ziqhekeke kulo.

Ukubaluleka: Amandla okutsalwa abalulekile kubunjineli nasekukhethweni kwezinto, njengoko ebonisa amandla ezinto zokumelana nemithwalo yokutsalwa esetyenzisiweyo ngaphandle kokusilela. Ichaphazela uyilo kunye nokusebenza kwezakhiwo, izinto kunye neemveliso.

Izinto Ezichaphazela Amandla Okuxinana: Amandla okutsalwa achaphazeleka zizinto ezahlukeneyo, kuquka ukwakheka kwezinto, ulwakhiwo lwazo, iindlela zokucubungula, ubushushu, kunye neemeko zokusingqongileyo.

Uthelekiso: Amaxabiso okuqina kokutsalwa avumela uthelekiso lweempawu zoomatshini zezinto ezahlukeneyo kwaye anceda iinjineli kunye nabayili ukuba bakhethe izixhobo ezifanelekileyo kwizicelo ezithile.

Ngokuqonda ezi nkalo zamandla okutsalwa, iinjineli kunye neengcali zezinto zinokwenza izigqibo ezinolwazi malunga nokukhetha izinto, uyilo, kunye nokuthembeka kwesakhiwo kumashishini ahlukeneyo kunye nokusetyenziswa kwazo.

Izinto Ezichaphazela Amandla Okuxinana

Amandla okutsalwa aphenjelelwa zizinto ezahlukeneyo, kuquka ukwakheka kwezinto, ulwakhiwo lwe-microstructure, iindlela zokucubungula, ubushushu, kunye neemeko zokusingqongileyo. Nantsi inkcazo eneenkcukacha ngakumbi yezinto ezichaphazela amandla okutsalwa:

Ukwakhiwa kwezinto: Ukwakheka kweekhemikhali kwezinto ezisetyenzisiweyo kuchaphazela kakhulu amandla azo okutsalwa. Izinto ezahlukeneyo kunye noxinzelelo lwazo zinokukhokelela kutshintsho kumandla eebhondi phakathi kweeathom okanye iimolekyuli ngaphakathi kwezinto ezisetyenzisiweyo.

Ulwakhiwo oluncinci: Ulwakhiwo lwangaphakathi lwezinto, kuquka ubungakanani beenkozo, imida yeenkozo, kunye nokusasazwa kwesigaba, kuchaphazela kakhulu amandla okutsalwa. Izinto ezicoliweyo zihlala zibonisa amandla aphezulu ngenxa yeendlela zokuqinisa imida yeenkozo.

Iindlela Zokucubungula: Indlela esetyenziswa ukuvelisa okanye ukubumba izinto inokuphembelela amandla azo okutsalwa. Umzekelo, iinkqubo zonyango lobushushu ezifana nokutsalwa, ukucima, kunye nokuthambisa zinokutshintsha ulwakhiwo lwezixhobo kunye neempawu zoomatshini, kubandakanya amandla okutsalwa.

Ubushushu: Amandla okutsalwa anokwahluka ngokweqondo lobushushu. Ezinye izinto zinokubonisa amandla aphantsi kumaqondo obushushu aphezulu ngenxa yokuthamba kobushushu, ngelixa ezinye zinokufumana amandla angakumbi ngenxa yokuqina koxinzelelo okanye ezinye iindlela.

Izinga loxinzelelo: Isantya apho into ikhubazeka khona sinokuchaphazela amandla ayo okutsala. Ezinye izinto zinokubonisa amandla aphezulu xa zitsala kakhulu ngenxa yobuthathaka besantya sokutsala, ngelixa ezinye zinokubonisa amandla aphantsi.

Iziphene kunye nokungafezeki: Ukubakho kweziphene ezifana nee-voids, i-inclusions, okanye i-dislocations kunokusebenza njengezinto ezixinanisayo zoxinzelelo kwaye kunciphise amandla okutsalwa. Ngokwahlukileyo koko, izixhobo ezineziphene ezimbalwa zihlala zibonisa amandla aphezulu okutsalwa.

Iimeko Zokusingqongileyo: Ukuchatshazelwa zizinto ezingqongileyo ezifana nokufuma, iikhemikhali, imitha, kunye nokugqwala kunokonakalisa amandla ezinto ngokuhamba kwexesha, nto leyo ekhokelela ekunciphiseni amandla okuxinana.

Izinto zokudibanisa: Ukongeza izinto zokudibanisa kwizinto ezisisiseko kunokuphucula amandla okutsalwa ngokusebenzisa ukuqinisa isisombululo esiqinileyo, ukuqinisa imvula, okanye ezinye iindlela zokuqinisa.

Izinga lokulayisha: Isantya apho izinto zilayishwa khona sinokuchaphazela amandla azo okutsalwa. Ezinye izinto zinokubonisa amandla ahlukeneyo phantsi komthwalo ongashukumiyo xa kuthelekiswa neemeko zomthwalo ezitshintshatshintshayo okanye ezijikelezayo.

Ukuqonda ezi zinto kunye nefuthe lazo kumandla okutsalwa kubalulekile ekukhetheni izinto, ukuphucula uyilo, kunye nokuqinisekisa ukuthembeka kwesakhiwo seenxalenye kunye neenkqubo kwizicelo ezahlukeneyo zobunjineli.
