!PLASTIC

Ufafanuzi wa nyenzo plastiki

Unapofafanua !PLASTIC, lazima pia ufafanue !ELASTIC ndani ya !MATERIAL hiyo hiyo.

Vigezo

YIELD        = MISES (Thamani ya chaguo-msingi), Mohr-Coulomb, DRUCKER-PRAGER, USER
HARDEN       = BILINEAR (Thamani ya chaguo-msingi), MULTILINEAR, SWIFT, RAMBERG-OSGOOD, KINEMATIC, COMBINED
DEPENDENCIES = 0 (Thamani ya chaguo-msingi) / 1
INFINITESIMAL    Ikibainishwa, dhana ya mgeuko mdogo hutumika

** Kuanzia mstari wa 2 na kuendelea **

Wakati YIELD = MISES (Thamani ya chaguo-msingi)

** Wakati HARDEN = BILINEAR (Thamani ya chaguo-msingi) **

(Mstari wa 2) YIELD0, H

** Wakati HARDEN = MULTILINEAR **

(Mstari wa 2) YIELD, PSTRAIN, Temperature
(Mstari wa 3) YIELD, PSTRAIN, Temperature

...inaendelea

** Wakati HARDEN = SWIFT **

(Mstari wa 2) ε0, K, n

** Wakati HARDEN = RAMBERG-OSGOOD **

(Mstari wa 2) ε0, D, n

** Wakati HARDEN = KINEMATIC **

(Mstari wa 2) YIELD0, C

** Wakati HARDEN = COMBINED **

(Mstari wa 2) YIELD0, H, C

Wakati YIELD = Mohr-Coulomb au Drucker-Prager

** Wakati HARDEN = BILINEAR (Thamani ya chaguo-msingi) **

(Mstari wa 2) c, $\phi$, H, $\psi$

** Wakati HARDEN = MULTILINEAR **

(Mstari wa 2) $\phi$, $\psi$
(Mstari wa 3) c, PSTRAIN
(Mstari wa 4) c, PSTRAIN

Aina nyingine za HARDEN = hupuuzwa na huwa thamani ya chaguo-msingi (BILINEAR).

Jina la kigeu Sifa Maelezo
YIELD0 　 R Mkazo wa awali wa kutiririka
H R Mgawo wa uimarishaji
PSTRAIN 　 R Mnyumbuko wa plastiki
YIELD R Mkazo wa kutiririka
\(\varepsilon0, K, n\) R \(\overline{\sigma} = k\left( \varepsilon_{0} + \overline{\varepsilon} \right)^{n}\)
\(\varepsilon0, D, n\) R \(\varepsilon = \frac{\sigma}{E} + \varepsilon_{0}\left( \frac{\sigma}{D} \right)^{n}\)
\(\phi\) R Pembe ya msuguano wa ndani
\(\psi\) R Pembe ya dilatancy (chaguo-msingi: thamani sawa na \(\phi\))
c R Cohesion
C R Mgawo wa uimarishaji wa kinematiki wa mstari
Temperature R Halijoto (inahitajika wakati DEPENDENCIES=1)
v1, v2...v10 R Konstanti za nyenzo

** Wakati YIELD= USER **

(Kuanzia mstari wa 2 na kuendelea) v1, v2, v3, v4, v5, v6, v7, v8, v9, v10

Mgawo wa ugumuishaji kwa kazi huhesabiwa kwa interpolesheni kutoka data ya ingizo iliyo hapo juu kwa halijoto au mnyumbuko wa plastiki uliobainishwa. Ni lazima kuingiza safu ileile ya PSTRAIN kwa kila thamani ya halijoto.
