ABSTRACT: In the presented work, the compressive behavior of circular cylinders, having certain size ratios and containing a notch with various configurations, was investigated through experimental and numerical studies. Nonlinear finite element analysis, using ABAQUS software, was conducted to evaluate the ultimate strength of the cylinders. The results were compared to those observed experimentally. The comparison of the numerical and experimental results showed that the nonlinear analysis results were more accurate than those established based on a linear analysis. The study also focuses on the deformed shape and stress distribution of the critical region in a notched cylinder for further consideration, e.g. repairing purposes.
