Soil mechanics is a branch of soil physics and applied mechanics that describes the behavior of soils. It differs from fluid mechanics and solid mechanics in the sense that soils consist of a heterogeneous mixture of fluids (usually air and water) and particles (usually clay , silt , sand , and gravel ) but soil may also contain organic solids ...
Terzaghi's principle applies well to porous materials whose solid constituents are incompressible - soil, for example, is composed of grains of incompressible silica so that the volume change in soil during consolidation is due solely to the rearrangement of these constituents with respect to one another.
This behavior, critical state soil mechanics simply assumes as a given. For these reasons, critical-state and elasto-plastic soil mechanics have been subject to charges of scholasticism; the tests to demonstrated its validity are usually "conformation tests" where only simple stress-strain curves are demonstrated to be modeled satisfactorily.
The Rankine lecture is an annual lecture organised by the British Geotechnical Association named after William John Macquorn Rankine, an early contributor to the theory of soil mechanics. This should not be confused with the biennial BGA Géotechnique Lecture. The Rankine Lecture is held in March each year.
Soil bulk density, when determined at standardized moisture conditions, is an estimate of soil compaction. [3] Soil porosity consists of the void part of the soil volume and is occupied by gases or water. Soil consistency is the ability of soil materials to stick together. Soil temperature and colour are self-defining.
The first modern theoretical models for soil consolidation were proposed in the 1920s by Terzaghi and Fillunger, according to two substantially different approaches. [1] The former was based on diffusion equations in eulerian notation, whereas the latter considered the local Newton’s law for both liquid and solid phases, in which main variables, such as partial pressure, porosity, local ...

In 1963, The American Society of Civil Engineers' Soil Mechanics and Foundations Division, along with and the friends of Terzaghi, established the Karl Terzaghi Lecture. The first lecture was delivered by Ralph B. Peck, a student of Terzaghi's, [19] in 1963. In 2016, the Geo-Institute of the American Society of Civil Engineers started observing ...
