The files contain geometric imperfection data of variable-angle filament-wound (VAFW) cylinders. The data is generated by the stitching algorithm described in the manuscript: Measurement of geometric imperfections for variable–angle filament–wound cylinders using a simple digital image correlation (DIC) set up. In that manuscript, the naming convention translates as follows. Cylinder name in the dataset <--> cylinder name in the manuscript: S1 <--> MA S2 <--> CA S4 <--> VAFW4 S8 <--> VAFW8 All coordinates (x,y,z) and the imperfection amplitude (imp) are in millimeters. Files: XXX_msi.txt contain imperfection in rectangular coordinates, represented by a cloud of points and their respective x,y,z position. Files: XXX_msi_theta_z_imp.txt contain imperfection in polar coordinates: theta, z, imperfection amplitude. These file formats are ready to be used with the DESICOS plug-in for Abaqus.
