Help on DEFORMATION

    Please prove that ,


    macroscopic strength rate=(burger's vector)*(dislocation density)*(average dislocation density)

    Why would you think this relationship holds? This would give "strength rate" the units of m-3, which seems unusual.

    The increase in strength from dislocation interactions is often modeled as (shear modulus)*(Burgers vector)*(square root of disl'n density).

    SORRY BUT IT WAS A TYPING ERROR! ACTUALLY IT WAS average dislocation VELOCITY!
    ALTHOUGH I have gave a new thread with modification!

    SUPERSOUVIK,

    Are you talking about the strengthening rate from work-hardening of the material?
