No ka loaʻa ʻana o ka ʻike piha a loiloialumini puaahana. ua hoʻokomo nā mea noiʻi i nā hōʻailona hōʻailona like ʻole. Eia nō naʻe, ʻo ka ʻike i kēia manawa o ke koʻikoʻi o kēia mau hōʻailona i ka nānā ʻana i ka hana o ka alumini foam i kaupalena ʻia. Hoʻohana kēia haʻawina i ke ʻano Generalized Regression Neural Network (GRNN) e hoʻokumu i kahi kumu hoʻohālike e hoʻopili ai i ka ʻikepili microstructure characterization o ka alumini me kona mau waiwai. Ma o ka CRNNmodel, ua unuhi ka poʻe noiʻi i ʻehā o nā hiʻohiʻona koʻikoʻi a me ko lākou mau koina kaumaha mai nā ʻano pore 13 o ka alumini foam. Ma hope mai, ua hoʻomohala ʻia kahi ʻano hoʻohālikelike hou, i kapa ʻia ʻo "Wang equivalent porosity"( WEP), ma o ka hoʻohana ʻana i ke koena kauuna i hāʻawi ʻia i nā hiʻohiʻona, a ua loaʻa nā coefficients ʻehā. Ke manaʻo nei kēia kumu e hōʻike i ka pilina ma waena o nā hiʻohiʻona microstructural foam alumini a me kāna hana mechanical, Eia kekahi, ua hana nā mea noiʻi i ka hōʻoia hoʻohālike me ka hoʻohana ʻana i ka ʻikepili kaomi mai 11 sets oalumini pahu. Ua hōʻike ʻia nā hopena hōʻoia ʻana ma waena o kēia mau waihona alumini foam 11. ka Gibson-Ashby formula i hōʻike i nā hopena anomalous i nā hihia ʻelua, ʻoiai ua hōʻike ʻo WEP i ke kūpaʻa kūʻokoʻa me ka ʻole o nā anomalies. I ka hoʻohālikelike ʻana i ka hoʻohālikelike ʻo Gibson-Ashby, ua hōʻike ʻo WEP i kahi 18.18% hoʻomaikaʻi maikaʻi ʻole i ka loiloi.

ʻO ka alumini foam, i haku ʻia me ka metala alumini a i ʻole kona mau ʻāpana, ua ʻike ʻia e kona ʻano porous he nui nā lua, a me kahi ʻano honeycomb-like. ʻO ka hoʻomohala ʻana i nā ʻano loiloi hoʻokō kikoʻī a paʻa loa e koi koke ʻia e hoʻomaikaʻi i ka hoʻohana ʻana i ka alumini foam.

ʻO ka Gibson-Ashby formulal a me ka Hanssen formulat, i hoʻokomoʻia e Gibson a me Ashby, he mea nui e like me nā hoʻohālikelike kuʻuna no ka weheweheʻana i nā mea hana mechanical o ka porous Akā naʻe,alumini pahuhōʻike i nā microstructures like ʻole a pili ʻia e nā ʻano kumu like ʻole, e like me ka porosity, ka nui o ka pore, a me ka hoʻohele pore. ʻO ka hapa nui o kēia mau pilina constitutive maʻamau he mau hiʻohiʻona phenomenological macroscopic ʻaʻole i helu i ka hopena o nā hale pore. Eia kekahi, ʻokoʻa nā koi o ka hana ʻana i ka alumini foam i nā hiʻohiʻona noiʻi like ʻole. No laila, pono e hoʻopili ʻia nā ʻano loiloi e hoʻokō i nā koi noi kikoʻī. Hoʻohui ʻia, nele ka māla alumini foam i nā ʻano hoʻokolohua maʻamau a me nā ʻāpana hana, e alakaʻi ana i nā luʻina a me ka hōʻoia ʻana i nā ʻike ma nā ʻano like ʻole. I ka hōʻuluʻulu ʻana, ʻaʻole hiki i nā hana kuʻuna ke hoʻokumu i ka pilina ma waena o nā ʻano microstructural o ka alumini foam a me kona mau hiʻohiʻona a i ʻole e hoʻohālikelike a wānana i nā waiwai mechanical foam alumini i loko o ka lewa. ʻO ka hilinaʻi wale ʻana i kahi hiʻohiʻona macroscopic no ka loiloi ʻana i nā waiwai mechanical o ka alumini foam ʻaʻole i hoʻokō hou i nā koi hoʻolālā hana o kēia wā. ʻO ka hoʻokumu ʻana i kahi pilina palapala ma waenaalumini puaaʻO nā ʻāpana hoʻonohonoho a me kona mau hiʻohiʻona mechanical he mea koʻikoʻi a pivotal.

I loko o kēia noiʻi ʻana, ua manaʻo ʻia kahi ʻāpana kikoʻī hou i kapa ʻia ʻo equivalent porosity e hōʻike i ka pilina ma waena o nā hiʻohiʻona microstructural a me ka hana o ka alumini foam. Ua loaʻa kēia ʻāpana mai ka mahele paona o nā hiʻohiʻona e like me ka porosity, ka nui o ka pore awelika, a me ka pōʻai o ka alumini foam. noʻonoʻo i ka hana o ka alumini foam.

Ma kēia noiʻi ʻana, hoʻohana mākou i kahi ala interdisciplinary ma ka hoʻohui ʻana i ka ʻepekema waiwai me ke aʻo ʻana i ka mīkini. Hoʻohui ʻia nā ʻenehana aʻo mīkini, e like me ke koho hiʻohiʻona, ka nānā ʻana i ke kaupaona ʻana, a me ke koena o ke kaupaona ʻana, e hoʻokumu i ka aformula no ka porosity like. Ua hōʻike mākou i ka pololei o ka porosity like ma ke ʻano he ʻano hōʻailona hou ma o ka hōʻoia ʻana o ʻelima mau hoʻohālike, e hāʻawi ana i kahi noʻonoʻo pololei o ka hana a ka alumini foam. Hāʻawi mākou i kahi ala ʻoi aku ka pololei no ka loiloi a me ka nānā ʻana i nā waiwai mechanical o ka mea, hāʻawi i nā kuhikuhi waiwai no ka hoʻoholo ʻana a me ka nānā ʻana. Hoʻopili pili ka noiʻi me ka holomua wikiwiki o ka ʻikepili nui a me nā ʻenehana naʻauao artificial ma o ka hoʻohui ʻana i ka noiʻi noiʻi ʻikepili me ke aʻo ʻana i ka alumini foam. Hoʻolauna mākou i nā ʻano hou a me nā ʻano hana, e hāʻawi ana i kahi hiʻohiʻona hou e pili ana i ke ʻano a me ka nānā ʻana i ka hana o ka alumini foam.
