1.Te kaha (σb): Ko te kaha teitei (Fb) ka pa ki tetahi tauira i te wa e toia ana, ka wehea e te ahotea (σ) ka puta mai i te waahi whiti taketake (So) o te tauira, ka kiia ko te kaha tensile (σb). σb), i roto i te N/mm2 (MPa).E tohu ana i te kaha morahi o te mea whakarewa ki te atete i te kino i raro i te taumahatanga.Kei hea: Fb - te kaha morahi o te tauira ka toia, N (Newton);Na - te waahi whiti taketake o te tauira, mm2.
2.ira tuku (σs): he mea whakarewa me te ahua hua, te ahotea ka taea te whakaroa haere tonu te tauira me te kore e piki te kaha (ka mau tonu) i te wa e toro ana, ka kiia ko te ira tuku.Mena ka heke te kaha, me wehe nga tohu o runga me raro.Ko te waahanga o te hua o te hua ko N / MM2 (MPA).Ira tuku o runga (σsu): te taumahatanga teitei i mua i te tukunga o te tauira ka heke tuatahi te kaha;Ira tuku raro (σsl): te ahotea iti i roto i te wahanga tuku i te wa e kore e kiia te paanga whakawhiti tuatahi.Kei hea: Fs - te kaha tuku (tonu) o te tauira i roto i te ngangau, N (Newton) Na - te waahi whiti taketake o te tauira, mm2.
3.Te whakaroa i muri i te wehenga: (σ) I roto i te whakamatautau tensile, ko te paheketanga o te pikinga o te roanga o te tauira i muri i te kumea atu i tana tauine ki te roa o te unahi taketake ka kiia ko te whakaroa.I whakahuahia i te σ, ko te waahanga te%.Kei hea: L1 - te roa o te tauira i muri i te toia o te tauira, mm;L0 - te roa o te ware taketake o te tauira, mm.
4.Te whakahekenga hautau: (ψ) I roto i te whakamatautau tensile, ko te tino whakahekenga o te horahanga whiti i tona whakahekenga i muri i te kumea atu o te tauira hei paheketanga o te waahi whiti taketake ka kiia ko te whakahekenga hautanga.Kua whakahuahia hei ψ, i te %.Kei hea: S0 - te waahi whiti taketake o te tauira, mm2;S1 - te iti rawa o te waahi whiti i te whakahekenga i muri i te unuhanga o te tauira, mm2.
5.Taupū mārō: te kaha o tētahi mea whakarewa ki te ātete i te kuhunga o tētahi mea mārō ki roto i te mata, e kīia ana he mārō.I runga i te tikanga whakamatautau me te whānuitanga o te tono, ka taea te wehea te pakeke ki te pakeke Brinell, Rockwell pakeke, Vickers pakeke, Shore pakeke, microhardness me te pakeke teitei pāmahana.Mo te ngongo e whakamahia ana i te brinell, Rockwell, he uaua ki te hunga e toru.
Te pakeke o Brinell (HB): Ma te whakamahi i te poi rino, carbide ranei o tetahi diameter, pehia te kaha whakamatautau (F) ki te mata o te tauira, tangohia te kaha whakamatautau i muri i te wa pupuri i tohua, me te ine i te diameter nuku (L) i runga i te mata o te tauira.Ko te uara pakeke o Brinell ko te quotient i whiwhi ma te wehewehe i te kaha whakamatautau ki te mata porohita o te nuku.Kua whakahuahia hei HBS (poroi rino) i te N/mm2 (MPa).
Ko nga paipa rino piauau wera e whakamahia nuitia ana i roto i te hanga, miihini, keri waro, umanga matū, hiko, waka tereina, umanga motuka, huarahi, piriti, ipu, whakaurunga hakinakina, miihini ahuwhenua, miihini hinu, miihini tirotiro me etahi atu ahumahi whakangao. .
Ko te putorino maitai piauau he putorino maitai paiherea me te ruku wera, te mata piauau hiko ranei.Ka taea e te piuauau te whakanui ake i te aukati waikura o nga putorino maitai me te whakaroa i te oranga o te ratonga.He maha nga whakamahinga o te paipa rino piauau, i tua atu i te whakamahia hei paipa mo nga wai pehanga iti penei i te wai, te hau me te hinu, ka whakamahia ano he paipa hinu me te paipa hinu i roto i te umanga hinu, ina koa i roto nga mara hinu moana, hei whakamahana hinu, whakamahana whakamahana me te whakamaarama waro me te whakawhiti hinu horoi mo nga taputapu coking matū, hei paipa anga tautoko hoki mo nga putunga paipa trestle me nga rua keri, aha atu.
Te paipa wai, te paipa hinu, te paipa scaffolding, te taiapa huarahi, te uhi whara, aha atu.
