ABSTRACT

This chapter delves deeper into the implications of the physical model. This physical basis derived from two scientific hypotheses: simple friction acting at interparticle contact areas of the load carrying particles governs soil shear; particles move into the steady-state flow structure at random shear strains i.e., as a Poisson process, causing this interparticle contact area over which the friction acts to decrease exponentially with strain. In contrast, the dynamical systems based soil model does not make such an assumption of homogeneity of deformation. For the case of soil shear, the change in stresses from their initial values is a function of the decrease in the interparticle contact area of particles that are not yet at the steady state. The chapter utilizes the standard method of science—testing hypothesis with empirical evidence (the test data), in an attempt to falsify the hypothesis.
