  2. 21. Impact response and delamination of composite plates

    Author : Robin Olsson; KTH; []
    Keywords : ;

    Abstract : This thesis covers a selection of issues associated with impact response and delarknation of composite plates. The problems include contact problems, impact response and delankration testing. READ MORE

  4. 22. Simulation of Delamination Initiation and Growth in Fiber Composite Laminates

    Author : Rikard Borg; Michael R. Wisnom; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis concerns the topic of delaminations in unidirectional fiber reinforced plastic composite laminates.A model for the simulation of delamination initiation and growth has been developed. It is based on fracture mechanics and formulated as a combination of a cohesive zone model and a linear elastic adhesive penalty formulation. READ MORE

  5. 23. A study on wear characteristics of high strength steels under sliding contact

    Author : Abdulbaset Mussa; Pavel Krakhmalev; Jens Bergström; Jens Hardell; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High strength steels; thread joint wear; punch wear; sliding wear; surface cracking; reciprocal sliding; fatigue; surface delamination; white etching layer; nano-structured layer; friction; Materialteknik; Materials Engineering;

    Abstract : In the last decades, significant improvements regarding the design, materials and technology of rock drills have been made. Likewise, in sheet metal forming, forming tools experience very high contact pressures when processing high strength steel sheets. READ MORE

  6. 24. On efficient modelling of progressive damage in composite laminates using an equivalent single-layer approach

    Author : Johannes Främby; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crash simulation; CFRP; adaptive delamination modelling; XFEM;

    Abstract : In order to reduce the weight and subsequently the fuel consumption of their vehicles, the automotive industry is currently very active in research to incorporate laminated composites of Carbon Fibre Reinforced Plastics (CFRP) into structural components. This effort is a reaction to the increasing demands from regulatory bodies aimed at reducing the CO2 emissions from the transportation sector. READ MORE
