stress, applied — The downward stress imposed at an aquifer boundary. It differs from effective stress in that it defines only the external stress tending to compact a deposit rather than the grain to grain stress at any depth within a compacting deposit [21] … Lexicon of Cave and Karst Terminology
Grain boundary strengthening — (or Hall Petch strengthening) is a method of strengthening materials by changing their average crystallite (grain) size. It is based on the observation that grain boundaries impede dislocation movement and that the number of dislocations within a … Wikipedia
stress, effective — Stress (pressure) that is borne by and transmitted through the grain to grain contacts of a deposit, and thus affects its porosity or void ratio and other physical properties. In onedimensional compression, effective stress is the average… … Lexicon of Cave and Karst Terminology
Grain growth — refers to the increase in size of grains (crystallites) in a material at high temperature. This occurs when recovery and recrystallisation are complete and further reduction in the internal energy can only be achieved by reducing the total area… … Wikipedia
Flow stress — is defined as the instantaneous value of stress required to continue deforming the material to keep the metal flowing. It is the Yield Strength of the metal as a function of strain, which can be expressed: [1] Yf = Ke^nYf = Flow stress, MPaK =… … Wikipedia
Critical resolved shear stress — is the component of shear stress, resolved in the direction of slip, necessary to initiate slip in a grain. It is a constant for a given crystal. Tests have been conducted on single crystals of metals to measure the shear stress required to… … Wikipedia
Strengthening mechanisms of materials — Methods have been devised to modify the yield strength, ductility, and toughness of both crystalline and amorphous materials. These strengthening mechanisms give engineers the ability to tailor the mechanical properties of materials to suit a… … Wikipedia

Yield (engineering) — The yield strength or yield point of a material is defined in engineering and materials science as the stress at which a material begins to deform plastically. Prior to the yield point the material will deform elastically and will return to its… … Wikipedia
