# Definition of a material law

These laws are usually referenced by materials to define a hardening type of a viscosity function. The list of all availables laws can be seen in Lois Matérielles.

lawno = lawset.define (numero, type)
lawno = lawset(numero)
lawno.put(param, value)
lawno.depend(param, fct, Key(Lock)))
...
 numero number of the material law (must be unique) type type of material (for example LinearIsotropicHardening) - see Lois matérielles param name of the law parameter (for example IH_SIGEL) value value of the law parameter fct function which characterizes the dependency of the property (optional: no fct if no dependency) Lock Lock which defines the dependency variable of the property (compulsory if there is a dependency)
