Calculating properties of real materials

Prop3D is a statistical micromechanics code that calculates overall properties of real materials, both statistically isotropic and anisotropic. The models are based on the Hashin–Shtrikman variational principle [1], in which the n-point probability functions are directly embedded in the mathematical theory. The program requires the probability functions computed using Stat3D for the computation [2, 3]. Some of the mechanical and thermal properties that Prop3D can calculate are given below.
