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

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

    Sammanfattning : 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. LÄS MER

  3. 2. Modelling of Delamination Growth in Composite Structures

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

    Sammanfattning : 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. LÄS MER

  4. 3. Dual Scale Porosity and Interlaminar Properties of Composite Materials

    Författare :Mohammad Waseem Tahir; Maline Åkermo; Stefan Hallström; Staffan Lundström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In the strive towards reduced fuel consumption and lower emissions, low structural weight is becoming a key factor in the design of advanced vehicle and aerospace structures. Whereas most traditional construction materials are seemingly reaching their limitations, composite materials with their high specific properties offer possibilities to further reduce weight.
