+====== Definition of a material law ======
+These laws are usually referenced by [[doc:user:elements:general:materials|materials]] to define a hardening type of a viscosity function. Examples of some available laws for isotropic hardening can be found in [[doc:user:elements:volumes:isohard|]].
+  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 [[doc:user:start#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'' | [[doc:user:general:locks|Lock]] which defines the dependency variable of the property (compulsory if there is a dependency) |
