  2. 11. Analysis and Applications of Minimum Quantity Lubrication (MQL)

    Author : Bulent Tasdelen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dry; compressed air; sliding; MQL; temperature; nozzle; oil amount; seizure; tool wear; tool-chip contact surface topography.; contact length;

    Abstract : One of the greatest obstacles to the implementation of MQL is “lack of knowledge” which also limits the expansion of its usage. The presented work aims to take a step toward a better understanding of the mechanisms that occur in MQL assisted machining. READ MORE

  5. 13. Sliding stability re-assessment of concrete dams with bonded concrete-rock interfaces

    Author : Alexandra Krounis; Stefan Larsson; Fredrik Johansson; Ignacio Escuder Bueno; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete dams; sliding stability; cohesion; shear strength; uncertainty; bond; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : The shear strength of the concrete-rock interface is an important parameter in sliding stability analyses of concrete dams founded on rock and depends, in addition to the normal stress state, on the bonding conditions of the interface; concrete-rock interfaces can be either unbonded, partially bonded or fully bonded.In the Swedish guidelines for dam safety all dam-foundation contacts are treated as unbonded.

  7. 15. Friction and wear in rolling and sliding contacts

    Author : Christer Spiegelberg; Sören Andersson; Roland Larsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tribology; friction; wear; rolling and sliding contacts; Engineering mechanics; Teknisk mekanik;

    Abstract : Mechanical products are always expected to perform better, last longer, be more environmentally friendly and preferably cost less. Rolling and sliding contacts are found in many mechanical products, and friction and wear in the contacts have a direct impact on the products’ ability to meet these demands. READ MORE
