• Characterization of three-dimensional microstructure of composite materials by X-ray tomography 

  Miettinen, Arttu (University of Jyväskylä, 2016)

  Analysis methods for X-ray microtomographic images of short fibre composite materials were developed. The methods enable estimation of microstructural properties of the material, e.g., aspect ratio and orientation of ...

• Effective elastic properties of biocomposites using 3D computational homogenization and X-ray microcomputed tomography 

  Karakoç, Alp; Miettinen, Arttu; Virkajarvi, Jussi; Joffe, Roberts (Elsevier BV, 2021)

  A 3D computational homogenization method based on X-ray microcomputed tomography (μCT) was proposed and implemented to investigate how the fiber weight fraction, orthotropy and orientation distribution affect the effective ...

• Analysis of microtomographic images of porous heterogeneous materials 

  Turpeinen, Tuomas (University of Jyväskylä, 2015)

  In this work, we study the phases of image processing chain of microtomographic imag- ing in order to obtain reliable results while optimizing the time spent on denoising and segmentation. We consider that the decisions ...

• Mechanical properties of natural fiber composites produced using dynamic sheet former 

  Pupure, Liva; Varna, Janis; Joffe, Roberts; Berthold, Fredrik; Miettinen, Arttu (Taylor and Francis, 2020)

  Composites formed from wood fibers and man-made cellulosic fibers in PLA (polylactic acid) matrix, manufactured using sheet forming technique and hot pressing, are studied. The composites have very low density (due to high ...

• Röntgenkuvantamisesta apua bentoniittipuskurin mallintamiseen 

  Harjupatana, Tero (Suomen atomiteknillinen seura, 2024)

  In this dissertation, a method for measuring water transport and deformation in swelling materials was developed. In the method, the wetting of a sample is monitored by taking X-ray or X-ray tomographic images at suitable ...
