Gisesengura uburyo bwo kunanirwa kwa 'groove wall gutanga' mumazu yoroshye ya aluminium.

Muri aluminium (urugero, 6061-T6), imbaraga z'umusaruro $ S_y \ hafi 35-40 $ ksi ziri munsi cyane ugereranije nimpeta yicyuma. Mu gusunika, impeta izenguruka ikora nk'icyuma kizunguruka, kandi umuvuduko mwinshi wo guhuza uganisha ku 'rukuta rutanga umusaruro.' Urukuta rwa groove ruhinduka uruzitiro, rutuma impeta yaguka kandi 'isohoka.' Ibi bikunze kumenyekana nko kunanirwa impeta. Igisubizo nukwongera ubujyakuzimu bwa $ G $, byongera agace kogosha $ A = D \ pi G $, cyangwa gukoresha 'umutwaro-ukwirakwiza' woge. Ba injeniyeri bagomba gukoresha formula $ P_ {yose} = \ frac {D \ pi G S_y} {2} $ kugirango barebe ko inzu ya aluminiyumu ishobora gushyigikira imitwaro isabwa.
