1. Performance index analysis of special-shaped steel pipe - plasticity
Plasticity inoreva kugona kwesimbi zvinhu kugadzira plastiki deformation (permanent deformation) pasina kukuvara pasi pemutoro.
2. Performance index analysis of special-shaped steel pipe - kuoma
Kuomarara inhamba yekuyera kuoma kwezvinhu zvesimbi.Iyo inonyanya kushandiswa nzira yekuyera kuomarara mukugadzira ndiyo indentation kuomarara nzira, iri kushandisa indenter ine imwe geometry kudzvanya mukati meiyo yakaedzwa simbi zvinhu pasi pemumwe mutoro, uye kuona kukosha kwayo kwekuoma zvinoenderana nedhigirii. ye indentation.
Nzira dzinowanzoshandiswa dzinosanganisira Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) uye Vickers kuoma (HV).
3. Performance index analysis of special-shaped steel pipe - kuneta
Simba, plasticity uye kuoma kwakakurukurwa pamusoro zvose zviratidzo zvemakanika zvinhu zvesimbi pasi pe static load.Muchokwadi, akawanda muchina zvikamu zvinoshanda pasi pe cyclic mutoro, uye pasi peichi mamiriro, kuneta kuchaitika.
4. Performance index analysis of special-shaped steel pipe - impact toughness
Iyo mutoro unoshanda pamushini nekumhanya kukuru unonzi kukanganisa kurodha, uye kugona kwesimbi kuramba kukuvara pasi pesimba rekuita kunonzi kukanganisa kuoma.
5. Performance index analysis of special-shaped steel pipe - simba
Simba rinoreva kuramba kwesimbi zvinhu kukundikana (yakawandisa epurasitiki deformation kana kutyoka) pasi static mutoro.Sezvo maitiro ekuita ekuremerwa achisanganisira tension, kudzvanya, kukotama uye kugera, simba racho rakakamurwa kuita simba rekusimba, simba rekumanikidza, kukotama simba uye kugera simba.Panowanzova nekubatana kwakati pakati pesimba rakasiyana-siyana.Kazhinji, kusimba kwesimba ndiyo inonyanya kukosha chiratidzo chesimba mukushandiswa.
