  1. 1. Continuum modelling of work hardening in precipitation hardened alloys

    Författare :Philip Croné; Jonas Faleskog; Peter Gudmundson; Norman Fleck; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid Mechanics; Hållfasthetslära;

    Sammanfattning : This thesis deals with prediction of macroscopic work hardening in a precipitation hardened alloy. The focus is on the particle contribution. A hierarchical modelling approach is adopted where work hardening in a representative material volume on the microscale is homogenized and used to represent the macroscopic hardening. LÄS MER

  3. 2. Thermo-Elasto-Hydrodynamic lubrication modeling of Tilting Pad Journal Bearings

    Sammanfattning : The journal bearing is a critical machine element typically used to support rotating motion in high speed machinery. Through the generation of a hydrodynamic pressure in its thin lubricant film,which is usually in the order of 10-100μmthick depending on the diameter of the journal itself, the bearing is able to withstand large loads, both statically and dynamically, while having a very low rate of wear.
