Ni ubuhe bwoko bw'umuyoboro w'icyuma ukoresha ductile ukwiriye umushinga wawe?

Dukurikije ibipimo ngenderwaho bya EN545, isuzuma ry'umuvudukoumuyoboro w'icyuma ukozwe mu cyumabigomba gukorwa ku bikoresho byose mbere yo gushyiraho irangi ryabyo ryo hanze n'iry'imbere, uretse irangi rya zinc ry'imiyoboro rishobora gushyirwaho mbere yo gukora isuzuma. Nta gusohora cyangwa kubira ibyuya bigomba kugaragara mu gihe cyo gukora isuzuma.

Icyitonderwa: Umuvuduko w’amazi ukoreshwa mu gukora ni muto ku byuma bikoreshwa mu gukora ibikoresho ugereranyije n’iby’imiyoboro kuko imiterere y’ibyuma bikoreshwa mu gukora ibikoresho ituma bigorana gutanga uburyo buhagije bwo kwirinda umuvuduko mwinshi w’imbere mu gihe cy’igeragezwa.

Kugira ngo dusobanukirwe neza uburyo EN545 igenzura ubukana bw'amazi asohoka, tugomba gusuzuma ingingo eshatu z'ingenzi: PEA, PMA, na PFA. Byose hamwe, bigize uburyo bwa siyansi bwo gusuzuma no kwemeza ubukana bw'amazi asohoka mu miyoboro.
1. PEA – Igitutu cyemewe cyo gukora
Ibi bivuga igitutu cy’imbere cyemewe mu miyoboro ku bushyuhe bwacyo ntarengwa, bigatuma imikorere yayo ihora ihagaze neza, mu mutekano kandi ihamye.

PEA = PMA+5bar

 2. PMA – Umuvuduko ntarengwa wemewe wo gukora

Ibi bivuga igitutu kinini cy’imbere cy’imiyoboro gishobora kwihanganira buri gihe ubushyuhe bw’icyumba, harimo n’igitutu cy’ubwiyongere bw’amazi.

PMA = PFA * 1.2

3. PFA - Igitutu cyemewe cyo gupima
Ibi bivuga igitutu ntarengwa umuyoboro ushobora kwihanganira mu gihe gito nyuma yo gushyirwaho na mbere yo gutangira gukoreshwa.   

PFA = (20 xe_umunotax R_m) / D x S_F

• Dufashe urugero rw'umuyoboro w'icyuma wa k9, e_umunotani ubugari bw'urukuta buke bw'umuyoboro, mm.
• R_mni imbaraga nkeya zo gukurura, N/mm².
• D ni umurambararo mpuzandengo w'umuyoboro, mm.
• S_Fni cyo kintu cy'umutekano.

umuyoboro w'icyuma wa k9, umuyoboro w'icyuma wa k9 wo mu bwoko bwa ductile, umuyoboro w'icyuma wa ductile upima umuvuduko,
