The study concerns computer simulation of dynamic piling-up behavior of dislocations emitted from the source against the grain boundary. The dynamic stress intensity factor by the dislocation piling-up was obtained in analytical equation in terms of stress application rate, grain size and materials constants. The comparison of the results was made with the static (equilibrium) result. Finally, the result was applied to the dynamic yielding strength of steel, and it is in good agreement with the experimental data in literature.
