Spam: Software for Practical Analysis of Materials - datasets for tutorials

Datasets for spam tutorials:

• VEC4 dataset from E.M. Charalampidou, E. Tudisco, S.A. Hall
  • Experimental details available here: Charalampidou, E.M. (2011), "Experimental study of localised deformation in porous sandstones", PhD Thesis
  • This dataset is two x-ray tomography scans of a notched sandstone sample scanned before and after deformation in an external rig.
    There is a rigid body displacement between the two scans that can be taken into account nicely with a registration.
    Scans from Laboratoire 3SR, Grenoble.
     
• M2EA05 dataset from E. Andò, G. Viggiani and J. Andrade.
  This data already used in the following papers for comparison to numerical simulations:
  • Kawamoto, R., Andò, E., Viggiani, G., & Andrade, J. E. (2016). Level set discrete element method for three-dimensional computations with triaxial case study. Journal of the Mechanics and Physics of Solids, 91, 1-13
  • Nadimi, S., Fonseca, J., Andò, E., & Viggiani, G. (2019). A micro finite-element model for soil behaviour: experimental evaluation for sand under triaxial compression. Géotechnique, 1-6
  • This dataset is a series of x-ray tomographies acquired during the triaxial compression of a small sample of a "Martian Simulant" soil, performed in Laboratoire 3SR, Grenoble.
     

• c01_F10_b4 dataset from O. Stamati, E. Roubin, E. Andò and Y. Malecot

  • This dataset belongs to a paper which is under review

  • This is a 4-binned x-ray tomography of a small cylindrical sample of micro-concrete
    Scans from Laboratoire 3SR, Grenoble.
     

• SandNX dataset from M. Milatz

  • The dataset is currently being analysed further

  • See this publication for the experimental setup: Milatz, M. (2020). An automated testing device for continuous measurement of the hysteretic water retention curve of granular media. Acta Geotechnica, 1-19
    Data acquired on NeXT-Grenoble, a simultaneous Neutron and X-ray scanner at the ILL in Grenoble (Experiment UGA-73).
    Neutron tomography has had a x0.7 downscale to bring it approximately in line with the pixel size for the x-ray tomography.
     

• YehyaConcreteNX dataset from M. Yehya, A. Tengattini, E. Andò, F. Dufour

  • Yehya, M., Ando, E., Dufour, F., & Tengattini, A. (2018). Fluid-flow measurements in low permeability media with high pressure gradients using neutron imaging: Application to concrete. Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 890, 35-42

  • Data acquired on NeXT-Grenoble, a simultaneous Neutron and X-ray scanner at the ILL in Grenoble (Experiment UGA-25).
