1. 41. Heterogeneous Bonded Particle Modelling of Rock Fracture

   Författare :Albin Wessling; Jörgen Kajberg; Simon Larsson; Pär Jonsén; Timo Saksala; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock; DEM; BPM; fracture; drilling; dynamic; Solid Mechanics; Hållfasthetslära;

   Sammanfattning : The dynamic fracture process of rock materials is of importance for several industries, such as the rock drilling process in geothermal and mining applications. Gaining knowledge and understanding of dynamic rock fracture through numerical simulations can enhance the rock drilling process, for example by optimising the drill bit geometry and drilling parameters.

4. 43. Linear and Nonlinear Mechanics of Lattice Materials : Computational Modelling and Experiments

   Författare :Danial Molavitabrizi; Mahmoud Mousavi; Kristofer Gamstedt; Haiyang Yu; Samuel Forest; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk fysik med inriktning mot tillämpad mekanik; Engineering science with specialization in Applied Mechanics;

   Sammanfattning : Lattice materials are artificial materials made of repeating unit-cells. The internal architecture of these materials can be engineered for a specific application such as energy absorption, heat transfer, or acoustic damping. LÄS MER

5. 44. On the Fracture of Thin Laminates

   Författare :Sharon Kao-Walter; Blekinge Institute of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laminate; interface; crack; adhesion; crack tip driving force;

   Sammanfattning : This thesis concerns mechanical and fracture properties of a thin aluminium foil and polymer laminate that is widely used as packaging material. The possibility of controlling the path of the growing crack propagation by adjustment of the adhesion level and the property of the polymer layer is investigated. LÄS MER

7. 45. Modelling the time-dependent, damage and fracture mechanical properties of load-bearing soft biological tissues

   Författare :Christopher Miller; T. Christian Gasser; Anna Pandolfi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid Mechanics; Hållfasthetslära;

   Sammanfattning : Load-carrying soft biological tissues exhibit a wide range of complex time-dependent, damage, and fracture mechanical properties. An effective comprehension of such behaviour is advantageous in characterising tolerance to injury and can provide valuable insights regarding the incidence and progression of certain diseases.
