  1. 1. Wrinkling of sandwich panels for marine applications

    Author : Linus Fagerberg; KTH; []
    Keywords : wrinkling; local buckling; imperfection; stability; anisotropy; sandwich;

    Abstract : The recent development in the marine industry with largerships built in sandwich construction and also the use of moreadvanced materials has enforced improvements of design criteriaregarding wrinkling. The commonly used Hoff’s formula isnot suited for the highly anisotropic fibre reinforced sandwichface sheets of today. READ MORE

  2. 2. Inflation and Instabilities of Hyperelastic Membranes

    Author : Amit Patil; Anders Eriksson; Arne Nordmark; Peter Hansbo; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membranes; Constrained inflation; Energy release rate; Adhesive contact condition; Limit point; Bifurcation point; Wrinkling; Tension field theory; Pressure induced instability.; Teknisk mekanik; Engineering Mechanics;

    Abstract : The applications of membranes are increasing rapidly in various fields of engineering and science. The geometric, material, force and contact non-linearities complicate their analysis, which increases the demand for computationally efficient methods and interpretation of counter-intuitive behaviours.
