Plasticity e bolela bokhoni ba lisebelisoa tsa tšepe ho hlahisa deformation ea polasetiki (deformation e sa feleng) ntle le tšenyo tlas'a mojaro.
2. Tlhahlobo ea index ea ts'ebetso ea tube ea tšepe ea lisekoere - boima
Ho thatafala ho lekanya hore na tšepe e thata kapa e bonolo hakae.Hona joale, mokhoa o atisang ho sebelisoa ho fumana hore na ho thata hakae tlhahiso ke mokhoa oa ho thatafala oa indenter, e leng ho sebelisa sebopeho se itseng sa geometri sa hlooho ea indenter tlas'a mojaro o itseng holim'a lisebelisoa tsa tšepe tse lekiloeng, ho latela tekanyo ea indenter ho fumana boleng ba boima ba yona.
Mekhoa e sebelisoang hangata ke Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) le Vickers hardness (HV) le mekhoa e meng.
3. Tlhahlobo ea index ea ts'ebetso ea tube ea tšepe ea lisekoere - mokhathala
Matla, polasetiki le boima bo boletsoeng ka holimo ke matšoao a lisebelisoa tsa tšepe tse tlas'a static loading.Ha e le hantle, likarolo tse ngata tsa mochine li sebetsa tlas'a meroalo ea cyclic, 'me mokhathala o ka hlaha tlas'a maemo ana.
4. Tlhahlobo ea index ea ts'ebetso ea pipe ea tšepe ea lisekoere - boima ba phello
Mojaro o sebetsanang le likarolo ka lebelo le phahameng o bitsoa " impact load", 'me bokhoni ba tšepe ba ho hanela tšenyo e tlas'a boima bo bitsoa ho tiea ha tšusumetso.
5. Tlhahlobo ea index ea ts'ebetso ea square steel tube - matla a lisekoere tsa tšepe, tube e teteaneng ea lisekoere tsa tšepe, tube e kholo ea lisekoere tsa tšepe, tube ea tšepe e se nang sekoere, tube e tlase ea tšepe, 135 * 135 * 10 square steel tube, tower crane square. tube tube, Q345B low alloy square steel tube, 20 # seamless square steel tube
Matla ke bokhoni ba thepa ea tšepe ho hanela ho hloleha (deformation e feteletseng ea polasetiki kapa fracture) tlas'a static loading.Ka lebaka la mokhoa oa ho jarisa ka mokhoa oa ho otlolla, ho hatella, ho koba, ho kuta, kahoo matla a boetse a arotsoe ka matla a tsitsitseng, matla a khatello, matla a ho koba, matla a ho kuta joalo-joalo.Hangata ho na le khokahano e itseng lipakeng tsa matla a fapaneng, 'me matla a ho tiea hangata a sebelisoa e le sesupa sa motheo sa matla.
Qetello ea sebopeho:pheletso e oblique, pheletso e bataletseng, e nyamele kapa eketsa sekoaelo sa polasetiki ho sireletsa lipheletsong ho latela litlhoko tsa bareki.
Theknoloji:ho bidika ho chesang, ho thetheha ho batang
