Description
| This dataset contains seven micro X-Ray Computed Tomography (micro-XRCT) scan data sets (projection, reconstructed, and segmented images, respectively) of an open-cell reticulated Polyurethane (PUR) foam specimen with 10 pores per inch under different uniaxial deformation states. The initial diameter and length of the unloaded cylindrical sample are 52 mm and 50 mm. The sample was glued on two aluminum sample holders. Scans of the sample were performed for seven successive time steps (t0, t1, t2, t3, t4, t5, t6) under uniaxial displacements of {0, 5, 10, 15, 20, 25, 0} mm imposed at the bottom part of the sample (fixed upper sample holder). Before starting the image acquisition at the different deformation states, the sample was relaxed for 20 min each time. The relaxation curves (including relaxation during the scan) are provided in the files "t*_utm_data.csv". The scans were performed displacement-controlled.
The image data sets are labeled according to the time step the micro-XRCT scan was performed (t0, t1, t2, t3, t4, t5, t6) followed by a specification of the image data set ("_projections", "_reconstructed", "_segmented"). Due to an eccentricity error between the upper and lower rotational table, compensation in the reconstruction was necessary. That was restricted to the foam part and not to the sample holders. Besides the projection images and the 3d reconstructed images, segmented images (into foam skeleton and void space) are provided. To reduce the data size, the foam sample was extracted by a cylinder of 52.36 diameter. Due to strong beam hardening in the aluminum sample holders, superimposed with cone-beam angle artifacts in those areas, and additional contaminated foam by the used glue in the transition region, only 44.26 mm in the axial direction of the foam sample at t0 (undeformed state) is given. For all other deformation states, the first and last slices of the segmented image stacks correspond roughly to them.
After the image acquisition and a sufficiently long relaxation of the sample, a uniaxial compression test up to 30 mm maximum displacement was performed using the same sample. Loading/unloading was performed displacement controlled with |0.5| mm/s. The data is provided in the file "utm_data.csv". |
