Pictorial
A quantity is the measurement of an observable property of a particular object, event, or physical system. A quantity is always associated with the context of measurement (i.e. the thing measured, the measured value, the accuracy of measurement, etc.) whereas the underlying quantity kind is independent of any particular measurement. Thus, length is a quantity kind while the height of a rocket is a specific quantity of length; its magnitude that may be expressed in meters, feet, inches, etc. Examples of physical quantities include physical constants, such as the speed of light in a vacuum, Planck's constant, the electric permittivity of free space, and the fine structure constant. In other words, quantities are quantifiable aspects of the world, such as time, distance, velocity, mass, momentum, energy, and weight, and units are used to describe their measure. Many of which are related to each other by various physical laws, and as a result the units of some of the quantities can be expressed as products (or ratios) of powers of other units (e.g., momentum is mass times velocity and velocity is measured in distance divided by time). These relationships are discussed in dimensional analysis. Those that cannot be so expressed can be regarded as "fundamental" in this sense. A quantity is distinguished from a "quantity kind" in that the former carries a value and the latter is a type specifier.
A Quantity Kind is any observable property that can be measured and quantified numerically. Familiar examples include physical properties such as length, mass, time, force, energy, power, electric charge, etc. Less familiar examples include currency, interest rate, price to earning ratio, and information capacity.
A Quantity Value expresses the magnitude and kind of a quantity and is given by the product of a numerical value n and a unit of measure U. The number multiplying the unit is referred to as the numerical value of the quantity expressed in that unit. Refer to NIST SP 811 section 7 for more on quantity values.
A unit of measure, or unit, is a particular quantity value that has been chosen as a scale for measuring other quantities the same kind (more generally of equivalent dimension). For example, the meter is a quantity of length that has been rigorously defined and standardized by the BIPM (International Board of Weights and Measures). Any measurement of the length can be expressed as a number multiplied by the unit meter. More formally, the value of a physical quantity Q with respect to a unit (U) is expressed as the scalar multiple of a real number (n) and U, as \(Q = nU\).

Vector

Ein linearer oder eindimensionaler Defekt, um den herum einige der Atome falsch ausgerichtet sind. Im Mesoscale ist eine Versetzung ein linienförmiges Objekt, das eine Grenze darstellt, die die Regionen auf der Gleitebene, in denen ein Gleiten stattgefunden hat, von denen trennt, in denen dies nicht der Fall war.
Linear or one-dimensional defect around which some of the atoms are misaligned. In the mesoscale, a dislocation is a line object that is a boundary separating the regions on the slip plane which have undergone slip from those that have not.
The presence of dislocation introduces local disturbance of the atomic-level geometry.
Dislocation
die Versetzung
Mathematical representation of dislocation as 'Line'. An instance of mathematical representation of a dislocation line is an oriented curve parameterized by its arc length.
Mathematische Darstellung der Versetzung als "Linie". Ein Beispiel für die mathematische Darstellung einer Versetzungslinie ist eine orientierte Kurve, die durch ihre Bogenlänge parametrisiert ist.

Cross Slip
A three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex.
Cube
Discrete dislocation dynamics (DDD) simulation is a simulation that is used to determine individual dislocation properties and study the distribution, arrangement, and density of dislocations in crystalline materials. The simulation observes the collective motion of many dislocations that links the relationship between the microstructure, loading conditions, and the mechanical properties of a crystalline material.
DDD Simulation
A Parameter that is used to run a DDD simulation.

Die Formfunktion ist die Funktion, die die Lösung zwischen den an den Netzknoten erhaltenen diskreten Werten interpoliert. Bei der diskretisierten Versetzung bestimmt die Formfunktion die Form eines Segments und letztlich die Form der Linie. Beispiele für Formfunktionen, die zur Diskretisierung der Versetzung verwendet werden, sind kreisförmig, elliptisch, spiralförmig, linear, kubisch und quintisch.
The shape function is the function that interpolates the solution between the discrete values obtained at the mesh nodes. In discretized dislocation, the shape function determines the shape of a segment and ultimately determines the shape of the line. Examples of shape function that is used to discretize the dislocation are circular, elliptic, spiral, linear, cubic, and quintic.
