These laws are usually referenced by materials to define a hardening type of a viscosity function. Examples of some available laws for isotropic hardening can be found in Isotropic hardening.
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) |
