Steel foams or porous steels can be successfully used in many engineering applications due to their unique chemical, physical and mechanical properties. In this research, due to the importance of studying the mechanical behavior of steel foams, the buckling behavior of this advanced and emerging engineering material has been simulated and investigated. For this purpose, explicit modeling of pores and the finite element method have been used. Studies were conducted for three different boundary conditions on models with porosity percentages of 0, 10, 20, 30, 37 and 45. Considering the novelty of the simulated problem, the issue of sensitivity to meshing was investigated. The results indicate that with increasing porosity, the number of elements increases and the critical buckling load decreases. The critical load values obtained for different models were compared with each other. The effect of porosity on buckling behavior is less for conditions where porous steel columns have more constraints.
