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

    Author : Daniel Svensson; Ulf Stigh; Bent Sørensen; Högskolan i Skövde; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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. Delamination of paperboard related to offset printing

    Author : Orlando Girlanda; Christer Fellers; Fredrik Thuvander; Jeffrey Suhling; Karlstads universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  6. 4. On Cohesive Modelling of Carbon/Epoxy Composites - Delamination and Fibre Compressive Failure

    Author : Daniel Svensson; Chalmers University of Technology; []
    Keywords : J-integral; Cohesive zone model; CFRP; Delamination; LEFM; Compressive failure;

    Abstract : Carbon Fibre Reinforced Polymers (CFRP) are widely used in engineering applications where weight saving and high mechanical performance are key factors. However, an inherent weakness of laminated CFRP:s is their relatively low resistance to delamination. READ MORE

  7. 5. Shear Fracture and Delamination in Packaging Materials : A study of Experimental Methods and Simulation Techniques

    Author : Md. Shafiqul Islam; Sharon Kao-Walter; Christian Johansson; Johan Tryding; Blekinge Institute of Technology; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Package opening; Shear test specimen; Stress intensity factor; Finite Element simulation; Scanning electron microscopy; Polymers; Interlaminar shear delamination;

    Abstract : Packages are the means of preservation, distribution and convenience of use for food, medicine and other consumer products. Package opening is becoming complicated in many cases because of cutting cost in design and production of opening techniques. READ MORE
