  1. 1. Mechanics of composites with fiber bundle meso-structure

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

    Abstract : 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. READ MORE

  2. 2. Micromechanics approach to stiffness characterization of woven composites
