  1. 1. Arterial mechanics : noninvasive identification of constitutive parameters and residual stress

    University dissertation from Linköping : Linköpings universitet

    Author : Jonas Stålhand; Linköpings universitet.; Linköpings universitet.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis concerns the mechanical modelling of arteries, and particularly a method to identify parameters describing the mechanical properties using only clinically obtainable in vivo measurements. The artery is modelled as a fibre reinforced, incompressible, thick-walled cylinder subjected to large deformations and a residual stress field. READ MORE

  2. 2. Active Control and Reduced-Order Modeling of Transition in Shear Flows

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Reza Dadfar; KTH.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SRA - E-Science SeRC ; SRA - E-vetenskap SeRC ;

    Abstract : In this thesis direct numerical simulation is used to investigate the possibilityto delay the transition from laminar to turbulent in boundary layer flows.Furthermore, modal analysis is used to reveal the coherent structures in highdimensional dynamical systems arising in the flow problems.

  3. 3. Transient acoustic fields studied by pulsed TV holography

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Staffan Schedin; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimentell mekanik; Experimental Mechanics;

    Abstract : Many of the acoustic events that reach our ears are produced by impacted and vibrating bodies. Pulsed holographic interferometry is a suitable technique to record transient events, like sound waves in air from an impacted body or the wave propagation in solid objects. READ MORE

  4. 4. Modeling of fracture and damage in rubber under dynamic and quasi-static conditions

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Elsiddig Elmukashfi; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid Mechanics; Hållfasthetslära;

    Abstract : Elastomers are important engineering materials that have contributed to the different technical developments and applications since the 19th century. The study of crack growth mechanics for elastomers is of great importance to produce reliable products and therefore costly failures can be prevented. READ MORE

  5. 5. On efficient and adaptive modelling of friction damping in bladed disks

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Mohammad Afzal; KTH.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High cycle fatigue; Friction contact; Jacobian matrix; Shroud contact; Strip damper; Multiharmonic balance method; Contact stiffness; Cyclic symmetry; Nodal diameter; Magnetostrictive actuator; Magnetic field; Teknisk mekanik; Engineering Mechanics;

    Abstract : This work focuses on efficient modelling and adaptive control of friction damping in bladed disks. To efficiently simulate the friction contact, a full-3D time-discrete contact model is reformulated and an analytical expression for the Jacobian matrix is derived that reduces the computation time drastically with respect to the classical finite difference method.
