The project is dedicated:

• definition of the link between the mechanical characteristics describing linear elastic properties crystalline solids at the micro and macro levels;
• definition of numerical values elastic characteristics at the micro level on the known experimental values elastic characteristics at the macro level.

It covers the following characteristics:

• at the micro level: the rigidity of the interatomic bonds;
• at the macro level: elastic material characteristics such as stiffness tensor components, the Young's modulus, Poisson's ratio, etc.
