  2. 1. ZrN based Nanostructured Hard Coatings : Structure-Property Relationship

    Author : Phani Kumar Yalamanchili; Magnus Odén; Naureen Ghafoor; Emilio Jiménez-Piqué; Jon Andersson; Linköpings universitet; []
    Keywords : ;

    Abstract : Ever since the hard coatings have been introduced, there has been a constant push for better mechanical properties, which motivates for deeper understanding of the microstructure-mechanical properties correlation. The aim of this thesis is to extend the knowledge on how microstructural variation influences the deformation, fracture and wear behavior of ZrN based nanostructured coatings. READ MORE

  4. 2. Structure-Control of the Rheological Behaviour of Particulate Gels

    Author : Camilla Olsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; structure formation; potato amylopectin; structure deformation; rheology; particulate gels; image analysis; beta-lactoglobulin; fracture mechanics; microstructure;

    Abstract : The focus of this thesis is the relation between the rheological and structural properties of mixed particulate gels, based on β-lactoglobulin, determined under both dynamic and static conditions. Rheological characteristics were recorded during formation of the gels, on set gels and during deformation and fracture of the gels, using viscoelastic measurements in shear and in compression and fracture mechanics in tension.

  5. 3. Computer Simulations of Polymer Gels : Structure, Dynamics, and Deformation

    Author : Natasha Kamerlin; Christer Elvingson; Jan Forsman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; computer simulations; Brownian dynamics; polymer gel; microgel; spherical boundary conditions; hypersphere; core-shell; deswelling; mechanical properties; uniaxial elongation;

    Abstract : This thesis presents the results of computer simulation studies of the structure, dynamics, and deformation of cross-linked polymer gels. Obtaining a fundamental understanding of the interrelation between the detailed structure and the properties of polymer gels is a challenge and a key issue towards designing materials for specific purposes.

  6. 4. Model-Based Investigation of Machining Systems Characteristics : Static and Dynamic Stability Analysis

    Author : Andreas Archenti; Mihai Nicolescu; Amir Rashid; KTH; []
    Keywords : Machining systems; modelling; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The increasing demands for precision and efficiency in machining call for new control strategies for machining systems based on the identification of static and dynamic characteristics under operational conditions. By considering the machining system as a closed-loop system consisting of a machine tool structure and a machining process, the join system characteristics can be analyzed. READ MORE
