Definition of a Material

A material is defined with the lines:

materialno = materialset.define (number, type)
materialno = materialset(number)
materialno.put(param, value)
materialno.depend(param, fct, Key(Lock)))
...
number number of the material (must be unique)
type type of material (for example EvpIsoHHypoMaterial) - see Materials
param code of the material parameter (for example MASS_DENSITY, or number of an evolution law such as YIELD_NUM, see General Points)
value value of the corresponding material 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)
