F.R. Larson and J. Miller proposed that creep rate could adequately be described by the Arrhenius type equation: r = A ⋅ e − Δ H / ( R ⋅ T ) {\displaystyle r=A\cdot e^{-\Delta H/(R\cdot T)}} Where r is the creep process rate, A is a constant, R is the universal gas constant , T is the absolute temperature , and Δ H {\displaystyle \Delta ...
The Hollomon–Jaffe parameter (HP), also generally known as the Larson–Miller parameter, [1] describes the effect of a heat treatment at a temperature for a certain time. [2] This parameter is especially used to describe the tempering of steels, so that it is also called tempering parameter.
The stress tending to shrink voids that must be overcome is related to the surface energy and surface area-volume ratio of the voids. For a general void with surface energy γ and principle radii of curvature of r 1 and r 2 , the sintering limit stress is [ 27 ] σ s i n t = γ r 1 + γ r 2 {\displaystyle \sigma _{\rm {sint}}={\frac {\gamma }{r ...
where E is the Young's modulus, ν is Poisson's ratio, and K I is the stress intensity factor in mode I. Irwin also showed that the strain energy release rate of a planar crack in a linear elastic body can be expressed in terms of the mode I, mode II (sliding mode), and mode III (tearing mode) stress intensity factors for the most general ...
I have merged in a few references from the Larson-Miller Parameter page, and made some comment regarding units. Not sure the units stuff is correct. Also I have recommended the Larson-Miller Parameter page be deleted as it is redundant and seems to be collecting contributions.67.87.139.9 04:06, 14 January 2014 (UTC)

In contrast to network related measures like throughput, QoE is typically not measured on ratio scales. Hence, fairness measures like Jain's fairness index cannot be applied, as the measurement scale requires to be a ratio scale with a clearly defined zero point (see examples of misuse for coefficients of variation).
Level of measurement or scale of measure is a classification that describes the nature of information within the values assigned to variables. [1] Psychologist Stanley Smith Stevens developed the best-known classification with four levels, or scales, of measurement: nominal, ordinal, interval, and ratio.
