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

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Daniel Svensson; Högskolan i Skövde.; Högskolan i Skövde.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technology; Teknik; Mechanics of Materials; Materialmekanik; CFRP; Cohesive zone model; J-integral; LEFM; Delamination; Compressive failure;

    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.

  2. 2. Delamination of paperboard related to offset printing

    University dissertation from Karlstad : Karlstads universitet

    Author : Orlando Girlanda; Karlstads universitet.; [2006]
    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; TECHNOLOGY Materials science; TEKNIKVETENSKAP 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

  4. 4. Shear Fracture and Delamination in Packaging Materials A study of Experimental Methods and Simulation Techniques

    University dissertation from Karlskrona : Blekinge Tekniska Högskola

    Author : Md. Shafiqul Islam; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

  5. 5. Experimental methods to determine model parameters for failure modes of CFRP

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Daniel Svensson; Högskolan i Skövde.; Högskolan i Skövde.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technology; composite; delamination; compressive failure; energy release rate; cohesive modelling;

    Abstract : The focus of this thesis is to develop methods to predict the damage response of Carbon Fibre Reinforced Polymers (CFRP). In the pursuit of reducing the manufacturing cost and weight of CFRP components, it is crucial to enable modelling of the non-linear response associated with various failure modes. READ MORE
