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:

Castro, S. G. P., Almeida, J. H. S., Jr., St-Pierre, L., & Wang, Z. "Measuring geometric imperfections of variable-angle filament-wound cylinders with a simple digital image correlation setup". Composite Structures, 2021. 10.1016/j.compstruct.2021.114497


In that manuscript, the naming convention translates as follows.

Cylinder name in the dataset <--> cylinder name in the manuscript:

S1 <--> MAS2 <--> CAS4 <--> VAFW4S8 <--> VAFW8

The geometry for all cylinders is:

Radius: 68 mmHeight: 300 mm

The nominal mass of each cylinder is:

S1: 148 gS2: 146 gS4: 149 gS8: 165 g

The mass of each cylinder can obtained with the measured thickness, assuming a mass density of 1600 kg/m^3:

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.
