Young Modulus is the slope of the stress-strain diagram in the linear elastic region. This is the most common use of modulus.
As the material goes non-linear in the stress strain curve, thre slope will get increasingly lower. In this case one connects the end points of the stress strain diagram at the point of interest with a straight line. The slope of that straight line is the secant modulus.
youngs modulus is modulus of elasticity which includes only elastic deformation where as deformation modulus or modulus of deformation include both elastic and inelastic deformation. In general, deformation modulus having less valve as compare to elastic modulus .
Depends on the hardness of the formulation. Poisson's ratio depends mainly on the bulk modulus and slightly on the Youngs modulus at very low strains for the subject compound. If the Youngs modulus lies between 0.92 and 9.40MN/m², Poisson's ratio lies between 0.49930 and 0.49993.

G = E/2(1+u) where G = mod of rigidity and u =poisson ration and E = young modulus
there are different types of modulus it depends on what types of stress is acting on the material if its direct stress then then there is modulus of elasticity,if tis shear stress then its modulus of rigidity and when its volumetric stress it is bulk modulus and so on
This is known as the Modulus of Elastisity, or Youngs Modulus (in tension/compression) and will be a constant as long as the deformation is in the elastic range.

Young's modulus is stress/strain. So if the modulus is high, it means that the stress value is greater compare to that of the material where the modulus is low. or in other words, the strain is very less compared to that of the material having low Young's modulus. So it tells that, if a material has high Young's modulus, the material requires more load for deformation of shape (within elastic limit).
young modulus remain unaffected ...as it depends on change in length ..
I think you mean "What variables affect young's modulus". Obviously not an english major!
Young's modulus-205 kN/mm2 Poisson's ratio = 0.30
