  2. Soil mechanics - Wikipedia

    en.wikipedia.org/wiki/Soil_mechanics

    The shear strength of soil is primarily due to interparticle friction and therefore, the shear resistance on a plane is approximately proportional to the effective normal stress on that plane. [3] The angle of internal friction is thus closely related to the maximum stable slope angle, often called the angle of repose.

  3. Compressive strength - Wikipedia

    en.wikipedia.org/wiki/Compressive_strength

    As per Indian codes, compressive strength of concrete is defined as: Field cured concrete in cubic steel molds (Greece) The compressive strength of concrete is given in terms of the characteristic compressive strength of 150 mm size cubes tested after 28 days (fck). In field, compressive strength tests are also conducted at interim duration i.e ...

  4. Mohr's circle - Wikipedia

    en.wikipedia.org/wiki/Mohr's_circle

    Mohr's circle is often used in calculations relating to mechanical engineering for materials' strength, geotechnical engineering for strength of soils, and structural engineering for strength of built structures.

  5. Effective stress - Wikipedia

    en.wikipedia.org/wiki/Effective_stress

    Erg Chebbi, Morocco. The effective stress can be defined as the stress, depending on the applied tension and pore pressure , which controls the strain or strength behaviour of soil and rock (or a generic porous body) for whatever pore pressure value or, in other terms, the stress which applied over a dry porous body (i.e. at =) provides the same strain or strength behaviour which is observed ...

  6. Critical state soil mechanics - Wikipedia

    en.wikipedia.org/wiki/Critical_state_soil_mechanics

    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]

  7. Shear strength (soil) - Wikipedia

    en.wikipedia.org/wiki/Shear_strength_(soil)

    Typical stress strain curve for a drained dilatant soil. Shear strength is a term used in soil mechanics to describe the magnitude of the shear stress that a soil can sustain. . The shear resistance of soil is a result of friction and interlocking of particles, and possibly cementation or bonding of particle contac

  8. Mohr–Coulomb theory - Wikipedia

    en.wikipedia.org/wiki/Mohr–Coulomb_theory

    Most of the classical engineering materials follow this rule in at least a portion of their shear failure envelope. Generally the theory applies to materials for which the compressive strength far exceeds the tensile strength. [1] In geotechnical engineering it is used to define shear strength of soils and rocks at different effective stresses.

  9. Compressive stress - Wikipedia

    en.wikipedia.org/wiki/Compressive_stress

    The ability of a material to withstand compressive stresses without failing is known as its compressive strength. When an object is subjected to a force in a single direction (referred to as a uniaxial compression), the compressive stress is determined by dividing the applied force by the cross-sectional area of the object.
