• 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 ...

• The effect of steric hindrance on the packing of elongated objects 

  Ekman, Axel (University of Jyväskylä, 2016)

  Fibres of various materials can be deposited to form planar mats of fibres. These kinds of structures have gained substantial attention owing to their direct relation to both large industrial fields, such as paper and ...
