E like me kā mākou e ʻike ai, ʻoiai ʻo ia ke ʻano likeuwea kila, ma muli o ke kaʻina hana kila, ʻaʻole like ke kaʻina hana kiʻi uea a me nā mea hana, no laila ʻaʻole like ka maikaʻi o ka hana uea kila.Ma muli o nāʻano mechanical likeʻole o ke kaula kila pono'ī, ke kaʻina hana a me nā mea hana,ʻo ka laulā a me ka lōʻihi o ke kaula kila i loko o ke kaʻina hana palahalaha he mau hopena likeʻole.No laila, i ke koho ʻana i ke anawaena uea, pono e noʻonoʻo ʻia nā kumu ʻekolu:
ʻO ka mea mua, ka hopena o ka ikaika tensile a i ʻole ka paʻakikī o ke kaula kila
He kiʻekiʻe ka ikaika tensile o ke kaula kila a he kiʻekiʻe ka paʻakikī.Ma ke kaʻina hana palahalaha, piʻi ka lōʻihi o ka neʻe ʻana o ka uea kila i kēlā me kēia ʻāpana leo a emi ka elongation.E neʻe ka leo ʻāpana uea kila i ke kūʻē ʻaoʻao liʻiliʻi, ka laulā o ka hoʻonui.ʻO ka mea ʻē aʻe, ua maʻalahi ka uwea e hoʻolōʻihi i ka lōʻihi, a e emi ana kona laula.ʻO kēia ka hana ʻana o ka uea kila kiʻekiʻe ʻoi aku ka maʻalahi o ka ākea, ka paʻakikī liʻiliʻi, maʻalahi ke kikoo i nā kumu ākea.Inā nui ka hoʻokaʻawale ʻana o ka ikaika tensile o ka uea kila, ʻilihune ka like ʻole o ka paʻakikī o ke kaula hao, ʻo ka ʻokoʻa ākea o ka billet i ʻōwili ʻia i ka nui, e hoʻopilikia nui i ka maikaʻi o ka billet.
ʻElua, ka mana o ka roughness ili uea kila
I ke kaʻina hana, inā ʻoʻoleʻa ka ʻili o ka uea kila, piʻi ka pānaʻi pili pili o ka uea kila a me ka ʻōwili, piʻi ke kūpaʻa friction, emi ka elongation uea kila, piʻi ka laulā.I ka hana ana o ka mea kaumaha ili mea maʻalahi i ka laulā, no ka mea, o kona ili ili.ʻO ka mea'ē aʻe, he maʻalahi kaʻili o ke kaula kila, no ka mea, heʻuʻuku ke kū'ēʻana ma waena o ke kaula kila a me ka'ōwili, hiki ke maʻalahi, a heʻuʻuku ka laulā.ʻO ka uea kila hale i mea e pale ai i ka ʻōpala, ʻo ka ʻili i uhi ʻia me ka pata, e like me ka wehe ʻana i ka pata ʻaʻole maʻemaʻe, maʻalahi ke paheʻe i ka wā e ʻōwili paʻa ai, pili pū i kona laulā.
ʻO ka hopena o ka hoʻohui kemika a me ke ʻano metallographic o ka uea kila
ʻO ke kiʻekiʻe o ke kalapona maʻiʻo o ke kila uea, ʻoi aku ka maikaʻi o kona plasticity, ʻoi aku ka liʻiliʻi o ka pauku ʻana a me ka elongation o ke kila uea, ʻoi aku ka paʻakikī o ka uea kila i ka rolling deformation, ʻo ka laulā o ka liʻiliʻi.No ka uea kila kila, no ka mea, hiki i ka mea hoʻoheheʻe i hoʻoheheʻe ʻia i loko o ka hopena paʻa ke hoʻomaikaʻi i ke anuanu paʻakikī paʻakikī o ka uea kila, ʻoi aku ka nui o kona kūpaʻa deformation, liʻiliʻi ka laula o ka ʻōwili, a maʻalahi ke haki.
