The plastic section modulus is used to calculate a cross-section's capacity to resist bending after yielding has occurred across the entire section. It is used for determining the plastic, or full moment, strength and is larger than the elastic section modulus, reflecting the section's strength beyond the elastic range. [1] Equations for the ...
An elastic modulus (also known as modulus of elasticity (MOE)) is a quantity that describes an object's or substance's resistance to being deformed elastically (i.e., non-permanently) when a stress is applied to it.
The elastic components, as previously mentioned, can be modeled as springs of elastic constant E, given the formula: = where σ is the stress, E is the elastic modulus of the material, and ε is the strain that occurs under the given stress, similar to Hooke's law.
The SI unit for elasticity and the elastic modulus is the pascal (Pa). This unit is defined as force per unit area, generally a measurement of pressure , which in mechanics corresponds to stress . The pascal and therefore elasticity have the dimension L −1 ⋅M⋅T −2 .
Diaspora is a hard science fiction novel by the Australian writer Greg Egan which first appeared in print in 1997. It originated as the short story "Wang's Carpets" which originally appeared in the Greg Bear-edited anthology New Legends (Legend, London, 1995). The story appears as a chapter of the novel.

Stresses in a contact area loaded simultaneously with a normal and a tangential force. Stresses were made visible using photoelasticity.. Contact mechanics is the study of the deformation of solids that touch each other at one or more points.
is the elastic modulus and is the second moment of area of the beam's cross section. I {\displaystyle I} must be calculated with respect to the axis which is perpendicular to the applied loading. [ N 1 ] Explicitly, for a beam whose axis is oriented along x {\displaystyle x} with a loading along z {\displaystyle z} , the beam's cross section is ...
