VAFW cylinders 2020, S1, S2, S4, S8, stitched imperfections

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.
