Statistical Details:
Large number of particles (near to infinity)
Statistical Ensemble (Beran 1968)
- Statistically the same even though different in the microscopic details
Infinitesimal volume element (?V)
- Exhibiting the same effective material property similar to that exhibited by the structure as a whole
Inhomogeneity:
- Properties may vary for ?V’s at different location (r)
Statistically Continuous Objects
- Random, disoriented objects
- Volume average =Ensemble Average
- ?ij (r)
