Effect of Rest Period on the Buckling of the 304 Stainless Steel under Increasing Loading

Abstract

Buckling plays a very important role in the design of slender columns. When the members are long, the loading, which is lower than yielding, may be large enough to cause the member to deflect laterally. It is well established that the mechanical surface treatments, e.g. shot peening, plasma peening and laser peening are effective method to enhance the resistance of metallic material. In this work, the main aim is to estimate the optimum improvement of dynamic behavior of medium carbon steel alloy due to shot peening experimentally. The behavior of rotating arcular column buckling of steel alloy under compression loading showed significant improvement due to shot peening time (SPT) at 25 mints. Which gave higher resistance against buckling and increasing the buckling time, after that the improvement tends to be reduced
