    Abstract : Shells are commonly used in many branches of engineering, and have therefore beeninvestigated for a number of different types of shells. A shell is considered to be curved aplate with small thickness compared both to the other geometrical dimensions as well asto the wavelengths of importance. READ MORE

  4. 4. Reinforcement in Tailor-made Concrete Structures

    University dissertation from Stockholm : Hållfasthetslära

    Author : David Fall; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tailor-made concrete structures; Steel fibre reinforcement; Automated production; Geometrically complex structures; Reinforcement alternatives;

    Abstract : In tailor-made concrete structures of complex geometries, the formability of concrete is an asset. To use this formability in load-bearing structures, the concrete needs to be reinforced. During the past century steel bars were used; however, in recent decades, alternative reinforcement methods have been introduced. READ MORE

  5. 5. Failure of thinwalled structures under impact loading

    University dissertation from Stockholm : Hållfasthetslära

    Author : Salar Mostofizadeh; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thinwalled shell structures; cohesive zone; phantom node method; ductile failure; XFEM;

    Abstract : Thinwalled structures are widely used for different applications, e.g. maritime structures,vehicles, off-shore structures, aircraft fuselage, ship panels etc., and due to their applicationthey might be exposed to high strain rate loads as blast loads. READ MORE
