This work aimed to develop a methodology to produce reliable buckling and post-buckling analyses for cylinders manufactured with composite material, taking into account imperfections generated by manufacturing. To accomplish this goal, the Abaqus® software, three (3) tools already implemented separately to the software and one (1) that served as input data for the process were used. TexGen4SC® is responsible for calculating the effective property of the bi-directional [0°/90°]2 fabric laminate, considering information from the specimen. The plug-in developed in the European DESICOS project helped the addition of thickness and average surface imperfections in Abaqus®, besides automating the creation of the resin rings, the contacts between rings and cylinder, and the boundary conditions. Moreover, a tool from Abaqus® is used to add a loading with imperfection, since the only specimen produced had a non-uniform load during the test. Finally, a subroutine developed at ITA and integrated into Abaqus® is used as an incremental damage model, i.e., to know if there would be any kind of damage during buckling and post-buckling of the cylinder. With the methodology defined, verification is made using already published data, guaranteeing a good functioning of the integrated analysis. From a comparison between the experimental and simulated results, it is possible to verify that, although influenced by the available methods for measuring imperfections and manufacturing the composite cylinder, the methodology follows a logical evaluation process, presenting satisfactory results for the uncertainties found. Therefore, the methodology showed followed an interesting reasoning flow but had its results affected by a specimen with more imperfections than expected, which brought a great increase of complexity to the work. Therefore, there is a great chance to produce more accurate results, such as showing the comparison with published data, but this requires better characterized mechanical properties, more accurate imperfection measurements and more suitable manufacturing processes to produce the specimen.
