  1. 1. Corotational formulation for nonlinear analysis of flexible beam structures

    Författare :Thanh Nam Le; Jean-Marc Battini; Jari Mäkinen; KTH; []
    Nyckelord :Corotational method; nonlinear dynamic analysis; beam element; large displacements; finite rotations; time stepping method; cubic interpolations;

    Sammanfattning : Flexible beam structures are popular in civil and mechanical engineering. Many of these structures undergo large displacements and finite rotations, but with small deformations. Their dynamic behaviors are usually investigated using finite beam elements. A well known method to derive such beam elements is the corotational approach. LÄS MER

  3. 2. Nonlinear dynamics of flexible structures using corotational beam elements

    Författare :Thanh-Nam Le; Jean-Marc Battini; Reijo Kouhia; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; corotational method; nonlinear dynamics; large displacements; finite rotations; time stepping method; thin-walled cross-section; beam element;

    Sammanfattning : The purpose of this thesis is to develop corotational beam elements for the nonlinear dynamic analyse of flexible beam structures. Whereas corotational beam elements in statics are well documented, the derivation of a corotational dynamic formulation is still an issue. LÄS MER

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Truck tyre; PRF; filler reinforced rubber; ambient temperature; rubber testing; parametrisation; Finite-element simulation; Lastbildäck; PRF; gummi; förstärkande fyllmedel; effekt av omgivningstemperatur; gummiprovning; parametrisering; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : Global warming sets a high demand to reduce the CO2 emissions of vehicles. In the European Union heavy-duty road transports account for 6 % of the total greenhouse gases and one of the main factors affecting these emissions is related to the rolling resistance of tyres. LÄS MER
