Ibanga lentsebenzo yebholiti, eyile ibakala lokwenziwa kwebholiti yoqhagamshelo lwesakhiwo sentsimbi, yahlulwe ibe ngamabakala angaphezu kwe-10, afana ne-3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, njl. Amacandelo amabini, ngokulandelelanayo amele ixabiso le-tensile lamandla kunye nomlinganiselo wamandla okugoba wemathiriyeli yebholithi.
Intsingiselo yomgangatho wokusebenza kwebholithi ngumgangatho jikelele wamazwe ngamazwe, ibholithi yomgangatho ofanayo wokusebenza, kungakhathaliseki umahluko wezinto zayo kunye nemvelaphi, ukusebenza kwayo kuyafana, uyilo lunokukhetha kuphela ibakala lokusebenza.
Amandla enqanaba le-8.8 kunye ne-10.9 ubukhulu bubhekiselele kwinqanaba loxinzelelo lokucheba lwebholithi yi-8.8 GPa kunye ne-10.9 GPa 8.8 amandla okuqina angama-800 n / 640 n yayizibholithi zamandla emveliso/yaye ngokuqhelekileyo ibonakaliswa ngamandla “XY”, X * I-100 = i-bolt yamandla e-tensile, i-X * 100 * (Y / 10) = amandla emveliso yebholithi (njengoko kuchaziwe kwilogo: isivuno / amandla okuqina = Y / 10, oko kukuthi 0. Y ebonisa) njengobukhulu be-4.8, Amandla okuqina ebholithi: 400 mpa. Amandla esivuno: 400 * 8/10 = 320MPa.Enye: iibholiti zentsimbi ezingenasici zidla ngokubhalwa A4-70, ukubonakala kwe-A2-70, oku kuthetha ukuba cacisa ngenye indlela imilinganiselo: iyunithi yokulinganisa ubude. kwihlabathi namhlanje kukho iintlobo ezimbini eziphambili, enye yemetric system, iyunithi yokulinganisa yimitha (m), iisentimitha (cm), mm (mm), njl., eYurophu, eChina naseJapan nakwezinye iindawo ezisemzantsi-mpuma yeAsia ngaphezulu, enye IsiNgesi, iyunithi yokulinganisa ubukhulu becala i-intshi (intshi), isetyenziswa kakhulu eUnited States, eBritani nakwezinye yaseYurophu kunye A.amazwe aseMelika.1.Umlinganiselo wenkqubo yemetric: 1m =100 cm=1000 mm2, umlinganiselo wenkqubo yesiNgesi: (8) 1 intshi =8 ints 1 intshi =25.4 mm
Iibholiti ezisetyenziselwa ukudityaniswa kwezakhiwo zentsimbi zinamabakala angaphezu kwe-10, kubandakanywa i-3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9 kunye ne-12.9. Ileyibhile yomgangatho wokusebenza weBolt iqulethwe ngamacandelo amabini, ngokulandelelana amele ixabiso lamandla anqabileyo kunye ukugoba amandla omlinganiselo wemathiriyeli yebholiti.Umzekelo: iibholithi ezinomlinganiselo wokusebenza 4.6, okuthetha ukuthi:
1. Amandla okuqina okuqhelekileyo okwenziwa kwebholithi afikelela kuma-400MPa;
2. Umlinganiselo wamandla okugoba we-bolt material ngu-0.6;
3. Amandla emveliso yebholithi afikelela kuma-400×0.6=240MPa iklasi
Ibanga lokusebenza 10.9 bolt amandla aphezulu, izinto zayo emva unyango ubushushu, unako ukufikelela:
1. Amandla okuqina okuqhelekileyo okwenziwa kwebholithi afikelela kwi-1000MPa;
2. Umlinganiselo wamandla okugoba we-bolt material yi-0.9;
3. Amandla emveliso yebholithi afikelela kwi-1000×0.9=900MPa iklasi
