He mea nui ngā papaaho tika o te karāneti i roto i ngā ahumahi e hiahia ana ki te tika me te pumau teitei, pērā i te ine ine, te hanga haurua-ira, me te miihini. Ko tētahi o ngā āhuatanga matua o te rauemi e tautuhi ana i te mahi a ēnei papaaho ko te "modulus elasticity," e kiia ana ko te modulus of elasticity. Ka pā tika tēnei tawhā ki te ātete o te papaaho ki te whakarerekētanga i raro i ngā kaha e pā ana, e whakarite ana i tōna whai huatanga i roto i ngā ine tika me ngā mahi tino tika.
Ko te modulus elastic o tētahi rauemi he ine i tōna pakari, e ine ana i te nui o tōna pirau i raro i tētahi kawenga kua hoatu. Ina koa, e whakaahua ana i te whanaungatanga i waenga i te ahotea (kaha mō ia wāhanga horahanga) me te taumahatanga (whakapoke) i roto i te rauemi ina pāngia e te pirau elastic. Ko te tikanga o te modulus elastic teitei he pakari ake te rauemi, ā, he iti ake te rerekētanga o tōna āhua i raro i te ahotea. Mō te karāhe, he rauemi pakari me te pakari, nā tōna modulus elastic teitei ka ātete ki te pirau, ahakoa i raro i ngā kawenga nui.
Mō ngā papaaho tika o te karāhe, he mea nui tēnei āhuatanga. He maha ngā wā ka whakamahia ēnei papaaho i roto i ngā tono e hiahia ana kia tino piripono ngā manawanui me te mahi pumau i roto i te wā. Ko te nui ake o te modulus elastic, ko te iti ake o te piko, te hē rānei o te papaaho i raro i te taumaha, kia mau tonu ai te tika o ngā inenga ahakoa kei te whakamahia te papaaho mō ngā wā roa, i raro rānei i ngā āhuatanga taiao rerekē.
Mā te pakari ā-roto o te karāhe ka āwhina i a ia ki te pupuri i tōna āhua ā-ira, he mea nui tēnei mō ngā mahi pēnei i ngā mīhini ine taunga (CMM) me ētahi atu taputapu ine tika. He mea nui te pumau o te rauemi kia kore ai e whakararuraruhia ngā hua e ngā whakarerekētanga kāore e hiahiatia, ka puta ai ngā hapa ine, ngā hapa rānei o te tūnga.
Heoi anō, ko te āhua ngāwari o te karāhe ka whai wāhi ki tōna kaha ki te mimiti me te whakaiti i ngā wiri. He mea nui tēnei i ngā wāhi ka pāngia e ngā wiri o waho te tika o ngā inenga. Ko te whakakotahitanga o te iti o te whakarerekētanga i raro i te kawenga me te ātete wiri teitei ka waiho te karāhe hei rauemi pai mō ngā papaaho tika e whakamahia ana i roto i ngā wāhi ahumahi tino tika.
Hei whakamutunga, ko te modulus elasticity o ngā papa tika o te karāhe he mea matua e tautuhi ana i tō rātou kaha ki te ātete i te whakarerekētanga i raro i te kawenga. Ka whakarite i te pumau, te tika, me te pono i roto i ngā tono ine nui, ka waiho te karāhe hei rauemi whiriwhiri mō ngā ahumahi e hiahia ana ki te mahi tika, rite tonu. Ahakoa i roto i te ine, te hangarau, te hanga rānei, he mea nui te modulus elasticity teitei o te karāhe ki te pupuri i te pono o ngā taputapu tika, e whai wāhi ana ki tōna whakamahinga whānui i roto i ngā tono mahi teitei.
Nā te huinga o te kaha me te pumau tēnei e tino whai hua ai ngā papaaho tika o te karāhe i roto i ngā taiao ahumahi tino uaua.
