Help on DEFORMATION: Strength Rate Calculation

[SUPERSOUVIK]

Please prove that ,


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

 

[Mapes]

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?
