Department of Theoretical and Applied Mechanics > "Crystal"
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.
