  3. 2. Impact Loading of Composite and Sandwich Structures

    Författare :Sohrab Kazemahvazi; Dan Zenkert; Guruswami Ravichandran; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : Low weight is one of the most important factors in the design process of high speed naval ships, road vehicles and aircrafts. Lower structural weight enables the possibility of down-sizing the propulsion system and thus decrease manufacturing and operating costs as well as reducing the environmental impact. LÄS MER

  4. 3. Failure of thinwalled structures under impact loading

    Författare :Salar Mostofizadeh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thinwalled shell structures; cohesive zone; phantom node method; ductile failure; XFEM;

    Sammanfattning : 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. LÄS MER

  5. 4. Failure of thin-walled structures under impact loading

    Författare :Salar Mostofizadeh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shells; rate dependence; Phantom node method; cohesive zone; Continuum damage; XFEM; ductile fracture;

    Sammanfattning : Increase in computational power during recent years contributed to a significant development in numerical methods in mechanics. There are many methods developed that address various complex problems, yet modelling of initiation and propagation of failure in thin-walled structures requires further development. LÄS MER

  7. 5. Concrete Structures Subjected to Blast Loading

    Författare :Jonas Ekström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic response; numerical modelling; spalling; blast load; stain-softening; wave propagation; concrete; transverse reverse loading; cyclic crack propagation;

    Sammanfattning : The interest for building safety with regards to highly dynamic events such as close by explosion has accelerated after the recent decades of terrorist attacks. The interest has expanded from civil defence shelters and pure military targets to also include civil buildings used for different civil functions. LÄS MER
