Multiscale microstructural characterization of particulate-reinforced composite with non-destructive X-ray micro- and nanotomography
Dastgerdi, J. Nafar; Miettinen, Arttu; Parkkonen, Joni; Remes, H. (Elsevier Ltd, 2018)Methods based on X-ray tomography are developed to study the relevant statistical quantities describing the microstructural inhomogeneity of particulate reinforced composites. The developed methods are applied in estimating ... -
Influence of Welding Time on Tensile-Shear Strength of Linear Friction Welded Birch (Betula pendula L.) Wood
Ruponen, Jussi; Cermák, Petr; Rhême, Martin; Miettinen, Arttu; Rohumaa, Anti; Rautkari, Lauri (North Carolina State University, 2015)The purpose of this work was to determine the optimal welding time for linear friction welding of birch (Betula pendula L.) wood while keeping the other parameters constant and at similar levels compared to other species ... -
Spectral analysis on optimizing X-ray tubes operating parameters and performance for non-destructive material quality analysis
Tarvonen, Jenna (2020)This Master's Thesis was made in cooperation with the University of Jyväskylä and Stresstech Oy. The purpose of this work is to compare the X-ray tubes from two different manufacturers (TruFocus and MRX), to obtain information ... -
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 ... -
