Fa'amatalaga o gaosiga
O le fa'aoga autu o le uamea fa'apipi'i nati o lo'o i totonu o galuega fa'ainisinia fausaga uamea e fa'afeso'ota'i ai nodes o le fausaga u'amea mafiafia ipu sila. Lelei faʻapipiʻi uiga, faʻaaogaina mo le fausaga uʻamea ma galuega faʻainisinia, o se faʻamaufaʻailoga. I le fausaga uʻamea lautele, o le uʻamea fausaga uʻamea manaʻomia e sili atu i le 8.8 vasega, o loʻo i ai foi 10.9,12.9. O fa'amau uma ia fa'amaua'a fa'ama'a'a maualuga. O nisi taimi o faʻamau i luga o le fausaga uʻamea e le faʻaogaina le eletise eletise, ae faʻaaoga le lanu muamua e mafai.
u'a fausaga u'amea ua vaevaeina i torsion-seleina uʻa malosi maualuga ma ulu hexagonal lapopoa malosi malosi. Lapo hexagonal malosi maualuga u'amea e patino i le maualuga toughness tulaga o sikulima lautele, torsional shear u'a malosi maualuga o se fa'alelei fa'alelei o le fa'aono fa'aono maualuga maualuga, ina ia sili atu le fausiaina o inisinia.
