  2. 1. On Cohesive Modelling of Carbon/Epoxy Composites : Delamination and Fibre Compressive Failure

    Author : Daniel Svensson; Ulf Stigh; Bent Sørensen; Högskolan i Skövde; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFRP; Cohesive zone model; J-integral; LEFM; Delamination; Compressive failure; Technology; Teknik; Mechanics of Materials; Materialmekanik;

    Abstract : Carbon Fibre Reinforced Polymers are widely used in engineering applications where weight saving and high mechanical performance are a key factors. However, an inheren tweakness of laminated CFRP:s is there relatively low resistance to delamination. Therst part of this thesis is devoted to extract cohesive laws associated with delamination.

  4. 2. Modelling of Delamination Growth in Composite Structures

    Author : Niklas E. Jansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; large deformation; interface; composite materials; 3D-shell; cohesive zone; regularization; shell element; delamination;

    Abstract : Delaminations constitute an important damage and failure mode in polymeric composite laminates. In order to explicitly incorporate and model the delamination progression within a finite element analysis, the meso-modelling concept is applied in the present work. The laminate is thereby represented by separate layers connected with interfaces. READ MORE

  5. 3. Delamination of paperboard related to offset printing

    Author : Orlando Girlanda; Christer Fellers; Fredrik Thuvander; Jeffrey Suhling; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical properties; Delamination; Finite Element Method; Paperboard; Z direction strength; Test equipment; Paperboard; Sheet Offset Printing; Web Offset printing; Shear stress; Modelling; Materials science; Teknisk materialvetenskap; Materialteknik; Materials Engineering;

    Abstract : The relationship between the behavior of paper during converting operations and the mechanical properties of paper are a fundamental issue for both paper producers and converters. In the attempt to establish these relationships and thus be able to judge the performance of paper, several testing methods have been developed. READ MORE
