This allows the material behaviour to be defined independently of the geometrical dimensions of the solid body of ... di- mension that must be analysed is often of the same order of magnitude as the maximum size of the discontinuities, which may be represented by the maximum dimension of the aggregates or by the distance ... the external forces. This set of relations defines the theory of stresses. This theory is completely independent of the properties of the material the body is made of, except that the continuity...
