Plasticity in a crystal of pure metal is primarily caused by two modes of deformation in the crystal lattice: slip and twinning. Slip is a shear deformation which moves the atoms through many interatomic distances relative to their initial positions.
Dialects can be defined as "sub-forms of languages which are, in general, mutually comprehensible." [1] English speakers from different countries and regions use a variety of different accents (systems of pronunciation) as well as various localized words and grammatical constructions.
This plot shows a typical meridional profile of several plasticity models: von Mises, linear Drucker–Prager, Mohr–Coulomb, Gurson, and Bigoni–Piccolroaz. The upper portion of the plot depicts yield surface behavior in triaxial extension and the lower portion depicts yield surface behavior in triaxial compression.
Plasticity (physics), in engineering and physics, the propensity of a solid material to undergo permanent deformation under load; Behavioral plasticity, change in an organism's behavior in response to exposure to stimuli; Neuroplasticity, in neuroscience, how entire brain structures, and the brain itself, can change as a result of experience

Language portal; This category contains both accents and dialects specific to groups of speakers of the English language. General pronunciation issues that are not specific to a single dialect are categorized under the English phonology category.
The plane stress, anisotropic, Hosford yield surface for four values of n and R=2.0. The Logan-Hosford yield criterion for anisotropic plasticity [2] [3] is similar to Hill's generalized yield criterion and has the form
In geotechnical engineering, rock mass plasticity is the study of the response of rocks to loads beyond the elastic limit. Historically, conventional wisdom has it that rock is brittle and fails by fracture , while plasticity (irreversible deformation without fracture) is identified with ductile materials such as metals .
