  5. 3. On folding of coated papers

    Author : Christophe Barbier; Per-Lennart Larsson; Tetsu Uesaka; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; folding; coated papers; finite element method; cracking; indentation; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : The mechanical behaviour of coated papers during folding has been investigated. This problem has been studied with experimental techniques and numerical analyses in order to give a better understanding of the folding properties of coated papers pertinent to the mechanical behaviour in general, and particularly cracking along the fold.

  6. 4. Modelling and simulation of plastic deformation on small scales : interface conditions and size effects of thin films

    Author : Per Fredriksson; Peter Gudmundson; Christian Niordson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strain gradient plasticity; Size effects; Thin films; Interface; Finite element method; Dislocations; Constitutive behaviour; Hardening behaviour; Indentation; Contact mechanics; Metal matrix composites; Engineering mechanics; Teknisk mekanik;

    Abstract : Contrary to elastic deformation, plastic deformation of crystalline materials, such as metals, is size-dependent. Most commonly, this phenomenon is present but unnoticed, such as the effect of microstructural length scales. READ MORE

  7. 5. Maturation-dependent normal and injury-induced changes in rabbit knee articular cartilage

    Author : Xiaochun Wei; Leif Ryd; Linköpings universitet; []
    Keywords : rabbit; development; maturation; knee joint; articular cartilage; osteochondral defect; cartilage repair; joint fluid; subchondral bone volume fraction; proteoglycan fragment; transforming growth factor-ß; biomechanics; indentation; histology; hlstomorphometry; MEDICINE; MEDICIN;

    Abstract : Cartilage injuries are common in sports, and may on the long term develop to osteoarthritis. Prosthetic joint replacement is not satisfactory for young active individuals with extended cartilage injuries in large weight-bearing joints. In these cases, a treatment is needed which reestablishes normal joint surfaces by biologic means. READ MORE
