WebbStress Strain Curve . Proportional limit is the point on a stress-strain curve at which it begins to deviate from the straight-line relationship between stress and strain. See accompanying figure at (1 & 2). Elastic limit is the maximum stress to which a specimen may be subjected and still return to its original length upon release of the load. WebbEquation 9.15 [F cr = π 2 EI/4L 2] is known as Euler’s column formula and indicates that the critical buckling load is not a function of the strength of the material (yield and ultimate strengths are not involved) but only of the elastic modulus and geometry.

WebbHooke’s Law states that the strain of the material is proportional to the applied stress within the elastic limit of that material. Mathematically, Hooke’s law is commonly expressed as: F = –k.x Where F is the force, x is the extension in length, and k is the constant of proportionality known as the spring constant in N/m.

Energy proportionality refers to the change in server energy consumption with utilization rate. It was proposed by Rysckbosch in 2007 , and its Formula (3) is as follows:

WebbThe proportional limit is the point on a stress-strain curve where the linear, elastic deformation region transitions into a non-linear, plastic deformation region. In other words, the proportional limit determines the greatest stress that is directly proportional to strain.
