  5. 4. Deformations and stresses in butt-welding of plates : numerical simulation and experimental verification

    Författare :Lars-Erik Lindgren; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Sammanfattning : Deformation and stresses in butt-welding of plates were studied. The work includes numerical simulation and experimental verification. The simulations were performed by use of the finite element method. Temperature dependence of material properties and phase transformations were considered. LÄS MER

  7. 5. On healing of titanium implants in biphasic calcium phosphate

    Författare :Christer Lindgren; Mats Hallman; Per Aspenberg; Lars Andersson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Background: Previously, autogenous bone was considered the gold standard for grafting procedures in implant surgery. Today, the use of bone graft substitutes is an alternative for sinus lift procedures. Nevertheless, only a few bone substitutes are well documented and can be recommended as an alternative to autogenous bone grafts. LÄS MER
