1. Zokolola
Pamene chitsulo kapena chitsanzo chikutambasulidwa, pamene kupanikizika kumadutsa malire otanuka, ngakhale kupanikizika sikukuwonjezeka, chitsulo kapena chitsanzo chikupitirizabe kupangidwa ndi pulasitiki yoonekeratu, yomwe imatchedwa kudzipereka, komanso kupanikizika kochepa pamene chinthu chololera chikuchitika. ndi ya zokolola.Lolani Ps kukhala mphamvu yakunja pa zokolola s, ndi Fo kukhala gawo lachitsanzo, ndiye zokolola σs = Ps/Fo (MPa)..
2. Kupereka mphamvu
Zokolola zazinthu zina zachitsulo ndizosawoneka bwino komanso zovuta kuyeza.Choncho, pofuna kuyeza makhalidwe a zokolola za zinthuzo, kupsinjika maganizo pamene pulasitiki yotsalira yotsalira imakhala yofanana ndi mtengo wina (kawirikawiri 0,2% ya kutalika koyambirira) imatchulidwa.ndi mphamvu zokolola zokhazikika kapena kungopereka mphamvu σ0.2.
3. Mphamvu yolimba
Kupanikizika kwakukulu kwamtengo wapatali komwe kumafikira pazinthu panthawi yotambasula, kuyambira pachiyambi mpaka kusweka.Imawonetsa kuthekera kwachitsulo kukana kusweka.Mogwirizana ndi mphamvu yamakokedwe, pali mphamvu zopondereza, mphamvu zosunthika, ndi zina zambiri. Lolani Pb ikhale mphamvu yayikulu kwambiri yomwe idakwaniritsidwa isanachotsedwe.
mphamvu, Fo ndiye gawo lagawo lachitsanzo, ndiye mphamvu yolimba σb = Pb/Fo (MPa).
4. Kutalikira
Zinthu zikasweka, kuchuluka kwa kutalika kwake kwa pulasitiki mpaka kutalika kwachitsanzo choyambirira kumatchedwa elongation kapena elongation.
5. Zokolola mphamvu chiŵerengero
Chiŵerengero cha chiwerengero cha zokolola (mphamvu zokolola) za chitsulo ku mphamvu zowonongeka zimatchedwa chiŵerengero cha zokolola-mphamvu.Kuchuluka kwa zokolola, kumapangitsanso kudalirika kwa zigawo zamagulu.Nthawi zambiri, zokolola chiŵerengero cha carbon zitsulo ndi 06-0.65, ndi otsika aloyi structural zitsulo ndi 065-0.75, ndi aloyi structural zitsulo ndi 0.84-0.86.
6. Kuuma
Kuuma kumasonyeza kuthekera kwa chinthu kukana kukanikiza kwa chinthu cholimba pamwamba pake.Ndi chimodzi mwa zizindikiro zofunika kwambiri za ntchito zachitsulo.Nthawi zambiri, kuuma kwapamwamba, kumakhala bwino kukana kuvala.Zizindikiro zowuma zomwe zimagwiritsidwa ntchito nthawi zambiri ndi Brinell hardness, Rockwell hardness ndi Vickers hardness.
