    Abstract : Mechanical Behaviour of Adhesive Layers Methods to Extract Peel and Mixed Mode Properties TOBIAS ANDERSSON Department of Applied Mechanics Chalmers University of Technology ABSTRACT This thesis is concerned with methods to extract material properties of thin adhesive layers loaded in peel and in mixed mode. The first part of the thesis is devoted to an experimental method to determine the complete stress-elongation relation (or cohesive law) for an adhesive layer loaded in peel using the DCB-specimen.

  5. 3. On the Modelling of Solid Phase Sintering of Hardmetal Based on Viscoplasticity

    Author : Lennart Mähler; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis is primarily concerned with issues related to the modelling of sintering of hardmetal, which is composed of WC-grains that are embedded in a Co-binder. The aims are to develop a constitutive model framework and computational tools by which it is possible, in a unified manner, to simulate the two subsequent steps of cold compaction and (free) sintering.
