Buckling load calculations are crucial for industry. This study examines experiments on two types of buckling columns: long and intermediate, both made from 304 stainless steel. 32 specimens were tested with and without shot peening (SP).The research aims to assess column loads in an oil field without corrosion, study corrosion effects, and evaluate dynamic buckling with fixed-pinned columns. Euler, Johnson, and Perry-Robertson formulas were used for calculations.An electrical Laser alarm triggered at 1% buckle deflection, stopping the test rig. Results were obtained without heat treatment,…mehr

Buckling load calculations are crucial for industry. This study examines experiments on two types of buckling columns: long and intermediate, both made from 304 stainless steel. 32 specimens were tested with and without shot peening (SP).The research aims to assess column loads in an oil field without corrosion, study corrosion effects, and evaluate dynamic buckling with fixed-pinned columns. Euler, Johnson, and Perry-Robertson formulas were used for calculations.An electrical Laser alarm triggered at 1% buckle deflection, stopping the test rig. Results were obtained without heat treatment, comparing experimental and theoretical values. Safety factors of 1.3 and 3 were needed to align experimental and theoretical results for Johnson and Perry-Robertson.Intermediate columns (diameter: 10 mm, thinness ratio: 112) showed the most improvement. Eroded columns in soil experienced a 28% (long) and 19.6% (medium) reduction in overturning load.The study suggests potential lifespan extension for 304 stainless steel, benefiting oil well operations and equipment longevity, with positive economic implications for oil-related activities.
