Answer
Mubisanzwe byamazi yimvura, igipimo $ b / t $ gifatwa ko ari kinini bihagije kugirango inyigisho zishyirwe mu bikorwa. Iyo $ b / t <8 $, isoko itwara bike nkibiti byoroshye kandi bisa nkibisahani bigoramye. Ikintu cyo gukosora $ C_f = \ frac {1} {1 - \ nu ^ 2} $, aho $ \ nu $ ari igipimo cya Poisson, rimwe na rimwe gikoreshwa kuri Modulus ya Elastique $ E_ {eff} = \ frac {E} {1 - \ nu ^ 2} $ kugirango ubare imbogamizi zinyuranye. Ku byuma bidafite ingese ($ \ nu \ hafi 0.3 $), ibi byongera ubukana bwa theoretical hafi 10%. Ikigeretse kuri ibyo, kurukuta ruciriritse cyane, ibyago byo 'kugoreka' cyangwa kuruhande-torsional bucking byiyongera, bisaba ko hakoreshwa ikintu gihamye muburyo bwo kubara.
