Variation of Elastic modulus with size

  1. Mar 24, 2013 #1
    It is generally well known that the elastic modulus of most materials become larger with decreasing size. This could be due to decreased number of dislocations, surface effects etc. Does any one know how exactly does this increase? Considering a ceramic or an oxide, how does the Elastic modulus E vary with a size parameter H?
