2. 1. A Damage-Based Interface Model: Application to the Degradation and Failure of a Polycrystalline Microstructure

   Author : Patrik Cannmo; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; damage; polycrystalline microstructure; degradation; slip and dilatation; interfaces; FE-calculations; viscoplasticity; plasticity; failure;

   Abstract : A constitutive model for material interfaces is presented. The model is based on damage coupled to plastic (or viscoplastic) slip and dilatation, and it is able to describe the successive degradation and failure of an interface. READ MORE

4. 2. Friction in highly pressurized lubricants and its relation to thermo-physical properties

   Author : Bert-Olof Åhrström; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

   Abstract : The objective of this work was to increase the understanding of which lubricant properties control transient friction, and during what environmental conditions friction is minimized. The experiments have been conducted during conditions relevant to an elastohydrodynamic contact, with pressures extending up to 2. READ MORE
