1. General description of crystalline behaviors

Crystalline behavior uses, in addition to DEFI_MATERIAU, DEFI_COMPOR.

The behavior name in COMPORTEMENT is generic: MONOCRISTAL or POLYCRISTAL.

The resolution algorithm is your choice:

• for MONOCRISTAL: NEWTON, NEWTON_RELI, NEWTON_PERT, and RUNGE_KUTTA

• for POLYCRISTAL: RUNGE_KUTTA

In this document, we describe:

• the architecture of DEFI_COMPOR

• the architecture of explicit error-controlled resolution by Runge-Kutta (cf. [R5.03.14])

• the architecture of the implicit resolution by Newton (environment PLASTI cf. [R5.03.14])

• internal objects useful for resolution.

To understand this document, reading R5.03.11 is strongly recommended.
