AbstractThe purpose of this paper is to estimate the optimum improvement of surface treatment on the dynamic buckling behavior of CK35 steel alloy due to shot peening based on the experimental results. Rotating circular column buckling test machine was used to evaluate the buckling life of column under compression and combined loading. The experimental results obtained show a favorable influence of shot peening treatment on mechanical properties and dynamic buckling behavior. A maximum significant life obtained at 25 min SPT (shot peening time) under dynamic buckling. The results showed that shot peening change the type of column from long to intermediate one based on Euler and Johnson formulas.
