Dataset for computational and experimental buckling analysis of constant-stiffness and variable-stiffness composite cylinders

his dataset encapsulates comprehensive information andexperimental outcomes derived from the buckling test ofvariable-stiffness composite cylinders subjected to axial com-pression. It is the first dataset about the correlation betweenexperimental and computational analysis for a Rapid-TowSheared composite cylinder, a recently developed advancedcomposite manufacturing technique.The data gathered during the test contains: raw test datafor force, end-compression and strain gauges; and digital im-age correlation. The data for finite element validation is for aquasi-isotropic shell and variable-stiffness rapid tow-shearedshell. The data also contain imperfection signatures from acoordinate-measurement machine (CMM) of both cylinders.This compilation of documented data stands as a robust re-source for future investigations, enabling comparative anal-yses, validation of theoretical models, and advancements inthe domain of designing and testing composite structures,particularly those employing variable-stiffness manufacturingtechniques.
