The DEFI_MATERIAU command can be re-entered but each behavior remains unique. Indeed, it is not possible to replace a behavior already present in the material but only to enrich the data structure with additional material characteristics.

Example of use:

Initially, only the thermal characteristics of the material are defined. Then, after thermal resolution, mechanical properties are added under ELAS:

ACIER_TH = DEFI_MATERIAU (THER =_F (LAMBDA =54.6,

                                     RHO_CP =3710000.0,),);

CHM = AFFE_MATERIAU (MAILLAGE = MAIL,

                         AFFE =_F (TOUT =' OUI ',

                                     MATER = ACIER_TH,

                                     TEMP_REF =20.0,),);

TEMPE = THER_LINEAIRE (MODELE = MODETH,...

ACIER_TH = DEFI_MATERIAU (reuse= ACIER_TH,

                         MATER = ACIER_TH,

                         ELAS =_F (E=204000000000.0,

                                     NU=0.3,

                                     ALPHA =1.092e-05,),);

RESUT = MECA_STATIQUE (MODELE = MODMECA,...
