Youngs Modulus
Can somebody give me a short defination of youngs modulus?
I think its the way a material acts under pressure, is this correct? |

The Young Modulus is proportionality constant between the stress and relative longitudinal deformation. The Young Modulus physical interpretetion is the resistence a solid has against stretching.
[tex] Y = \frac{\sigma}{\delta L} [/tex] |

Young's modulus for linear-elastic tension / compression, Hookean material in its simplest form (uniaxial deformation like a rod or something like) :
[tex] E = \frac {\sigma L}{\delta} [/tex] where [tex] \sigma [/tex] is the applied uniaxial stress, [tex] \delta [/tex] the displacement and L the length (initial) of the rod or reference in question (so in this form it is essentially a 1D construct with infinitesimal deformations). |
