Answer
Impera yimpande ($ Y $) nintera iri hagati yimpera yigitereko cyangwa amazu hamwe na groove. Niba impera yimpande ari nto cyane, urukuta rwa groove ruzananirwa binyuze muri shear cyangwa 'blowout' mbere yuko impeta inanirwa. Imbaraga zogosha za groove zibarwa nka $ P_ {shear} = \ pi \ cdot D \ cdot Y \ cdot \ tau $, aho $ \ tau $ nimbaraga zo gukata ibikoresho bya groove ($ \ hafi 0,6 \ cdot \ sigma_y $). Amategeko ngenderwaho asanzwe yubuhanga ni uko inkombe $ Y $ igomba kuba byibuze $ 3 $ inshuro zimbitse $ d $ kugirango barebe ko impeta yananiwe gukata mbere yuko urukuta rwa ruhago rucika. Mubikorwa byindege, aho uburemere ari ingenzi, isesengura ryibintu bitagira ingano (FEA) rikoreshwa kenshi mugutezimbere $ Y $ mugihe hagumyeho umutekano wamadorari 1.5 $ yo kurwanya inkovu.
