Theoretical soil mechanics is continuum mechanics adapted to soil, a granular material. Continuum mechanics is a complicated, subtle and difficult science. It suffers from fragmentation; its notation is not unique, and the degree of mathematical abstraction varies greatly. Some researchers get lost in it. Themany diverse numerical applications add to the confusion; their continuum mechanical foundations are often hidden. These aspects imply a declining interest in continuum mechanics for soils, which is also enhanced by the emergence of computer-based micromechanical methods. Instead of the continuum, agglomerates of individual particles are considered. This approach has its merits but still does not provide a global understanding for the behaviour of soil. Certainly, the continuum is an abstraction, just like the mass point of classical mechanics. The discontinuous structure of matter (such as sand) can be reconciled with the assumption of the continuum by considering the continuously distributed field quantities as expected values of discontinuous distributions.
