Abstract:
1. Method to identify the mechanical properties of a material, comprising: a first step comprising acquiring at least a digital image of a sample of said material, said digital image comprising elementary units a second step comprising acquiring, for every elementary unit of said digital image, at least a predetermined indicative parameter indicating at least one member of the group consisting of the presence of matter in said elementary image unit, the absence of matter in said elementary image unit, and type of matter in said elementary image unit, a third step comprising constructing a grid of elementary geometric elements, or cells, able to be associated with said digital image, a fourth step comprising assigning, for each of said cells, an index representative of the characteristics of the type of matter that occupies the position of a relative cell in relation to the parameters possessed by the elementary image units associated with such cell, a fifth step comprising defining the mechanical characteristics of each cell according to said index and the mechanical properties of the type of matter, and a sixth step comprising determining the mechanical properties of said material on the basis of numerical simulations carried out using the Cell Method.
