  5. 4. Deployment Control of Spinning Space Webs and Membranes

    Författare :Mattias Gärdsback; Anders Eriksson; Gunnar Tibert; Thomas W. Murphey; KTH; []
    Nyckelord :Flexible structures; space webs; membranes; solar sails; solar power systems; deployment control; optimal control; centrifugal force deployment; spin deployment; rotation-free; shell elements; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Future solar sail and solar power satellite missions require deployment of large and lightweight flexible structures in space. One option is to spin the assembly and use the centrifugal force for deployment, stiffening and stabilization. LÄS MER

  7. 5. 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
