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

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

    Abstract : 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. READ MORE

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear acoustics; nondestructive testing; activation density; slow dynamics; resonance frequency; nonlinear wave modulation spectroscopy; harmonic generation; trapped modes; open resonator; sweep rate;

    Abstract : Sensitive nonlinear acoustic methods are suitable for material characterization. This thesis describes three nonlinear acoustic methods that are proven useful for detection of defects like cracks and delaminations in solids. READ MORE

  6. 14. Self-organization and Intervention of Nonlinear Multi-agent Systems

    Author : Yuecheng Yang; Xiaoming Hu; Torkel Glad; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-agent system; linear system; nonlinear system; opinion dynamics; crowd dynamics; leader-follower based model; optimal control; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Abstract : This dissertation concerns the self-organization behaviors in different types of multi-agent systems, and possible ways to apply interventions on top ofthat to achieve certain goals. A bounded confidence opinion dynamics modelis considered for the first two papers. READ MORE

  7. 15. Nonlinear Dust Particle Dynamics and Collective Effects in Complex Plasmas

    Author : Gianfranco Sorasio; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Complex Dusty Plasmas; Self excited; Nonlinear; Forced Oscillations; Electrostatic Instabilities in current-carrying magnetoplasmas; Cross-field instabilities in magnetized dusty plasmas; Dust Acoustic Waves; Electrostatic Dust Cyclotron Waves; Fysik; Physics; Fysik; fysik; Physics;

    Abstract : Theoretical studies of dusty plasmas have been performed by focusing attention principally on collective phenomena and on grain motion. This thesis consists of a collection of seven published papers that explore both the collective behavior of a complex plasma system as well as the dynamics of grains in plasmas. READ MORE
