Buckling columns resistenes using liquid nitride case hardening method

Abstract EN

In this research buckling of circular columns under different dynamic loads is investigated by using analytical and experimental approaches.

Carbon steel columns (C35)of different slenderness ratio were studied .In this work Liquid nitriding method was used to improve the buckling resistance of materials.

The present study showed experimentally that the use of nitride case hardening increase the buckling resistance and improve the number of failure cycles ,for Steel a number of failure cycles increased from(2.6) to (4.1) cycle.

The results also showed that the thickness of nitride case hardening (28-45) micron play an important factor in buckling resistance .
