1. 1. Modelling of fracture toughness using peridynamics : A Study of J-integral, essential work and homogenisation

   Författare :Christer Stenström; Pär Jonsén; Kjell Eriksson; Ugo Galvanetto; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Peridynamics; J-integral; Essential work of fracture; Nonlocal methods; Meshless; Meshfree; Fracture; Crack tip; Exact analytical; Center cracked tension; Double edge notched tensile; fracture toughness; Peridynamik; Brottmekanik; Sprickspets; Brottseghet; Spänningsintensitet; Hållfasthetslära; Solid Mechanics;

   Sammanfattning : Fracture toughness is one of the most important properties of a material. Being able toaccurately estimate the energy that goes into forming new crack surfaces is essential for the development of new materials, quality assurance, structural monitoring and failure analysis.

3. 2. Mechanics of composites with fiber bundle meso-structure

   Författare :Normunds Jekabsons; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

   Sammanfattning : The presented thesis analyze mechanical phenomena in fibrous composites with fiber bundle sub-structure (woven composite sheet molding compounds (SMC) etc.). This sub-structure defines an intermediate meso-scale between the scale of individual fibers and macro-scale of the composite. LÄS MER
