4. Internal objects for storing information

The material coefficients are read only once per integration point in the LCMMAT/LCMMAP routines. The quantities read (or calculated, in the case of orientation tensors) must be passed to the integration routines. For this we use specific tables: nbcomm, coeft/materf, cpmono, toutms…)

4.1. In the case of monocrystals:

Storage of information relating to single crystals in specific tables (nbcomm, coeft/materf, materd, cpmono,).

MATERF: material coefficients a t+dt

subdue (*,1) = elastic characteristics

subdue (*,2) = plastic characteristics

MATERD: material coefficients at t

NBCOMM (*.3): POSITION DES COEF POUR CHAQUE SYSTEME

integer array

for each family of sliding systems:

Family 1 ind coef ind coef ind coef

…

ind means the clue in MATERF/MATERD (*,2)

last line: number of families

CPMONO: array of character strings, copy of the sd_compor object. CPRK

by family of sliding systems

Family name

Material name

Name of the law of flow

Name of the isotropic work hardening law

Name of the law of kinematic work hardening

4.2. In the case of polycrystal:
