!PLASTIC¶

Plastik materialni aniqlash

!PLASTIC aniqlanganda, ayni !MATERIAL ichida !ELASTIC ham birga aniqlanishi kerak.

Parametrlar¶

YIELD        = MISES (sukut bo‘yicha), Mohr-Coulomb, DRUCKER-PRAGER, USER
HARDEN       = BILINEAR (sukut bo‘yicha), MULTILINEAR, SWIFT, RAMBERG-OSGOOD, KINEMATIC, COMBINED
DEPENDENCIES = 0 (sukut bo‘yicha) / 1
INFINITESIMAL    ko‘rsatilsa, kichik deformatsiya farazi qo‘llanadi

Ishlovda qattiqlashish koeffitsiyenti yuqoridagi kirish ma’lumotlaridan belgilangan harorat yoki plastik nisbiy deformatsiya bo‘yicha interpolatsiya qilish orqali hisoblanadi. Har bir harorat qiymati uchun bir xil PSTRAIN massivi kiritilishi kerak.
