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.
Elastic modulus is the unit of measurement of an object's or substance's resistance to being deformed elastically when a stress is applied to it. Learn about the definition, types, and calculation methods of elastic modulus, and how to use DFT to determine it.
Atterberg limits are measures of the critical water contents of fine-grained soils that define their states and properties. Learn how to perform the liquid limit, plastic limit and shrinkage limit tests, and how to use the derived limits such as plasticity index and liquidity index.
A soil classification system used in engineering and geology to describe the texture and grain size of a soil. The system uses a two-letter symbol to indicate the percentage of gravel, sand, silt, clay, organic matter and liquid limit of the soil.
Viscoelasticity is the property of materials that exhibit both viscous and elastic characteristics when undergoing deformation. The web page explains the background, types, and applications of viscoelasticity, but does not mention Maxwell models or their relation to viscoelasticity.
It's the point at which the soil cannot sustain any additional load without undergoing continuous deformation, in a manner similar to the behaviour of fluids. Certain properties of the soil, like porosity, shear strength, and volume, reach characteristic values. These properties are intrinsic to the type of soil and its initial conditions. [1]
Elasticity is the ability of a body to resist a distorting influence and to return to its original size and shape when the influence is removed. Learn about different kinds of elasticity, such as linear, nonlinear, and viscoelastic, and how they are measured by elastic moduli and stress-strain curves.
Learn about the factors and theories that affect the shear strength of soil, which is the magnitude of the shear stress that a soil can sustain. Find out the difference between undrained and drained shear strength, and how to calculate them using Tresca, Mohr-Coulomb and critical state models.
