  1. 1. Active Health Monitoring of Aerospace Composite Structures by Embedded Piezoceramic Transducers

    Detta är en avhandling från Institutionen för flygteknik

    Författare :Christophe Paget; KTH.; [2001]
    Nyckelord :embedded; piezoceramic; piezoelectric; transducer; composite; structural; integrity; health monitoring; damage detection; Lamb waves; wavelets; normal-mode expansion; FE-method; SLMT;

    Sammanfattning : The objectives of the thesis work were to study theinteraction between embedded piezoceramic transducers andcomposite structures as well as determine techniques tosimplify the Lamb waves analysis. Firstly, this studyconsidered the design of the embedded piezoceramic transducers. LÄS MER

  2. 2. Structural integrity of prestressed nuclear reactor containments

    Detta är en avhandling från KFS AB

    Författare :Patrick Anderson; Lunds universitet.; Lund University.; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reliability; steel liner; relaxation; shrinkage; creep; loss of prestress; tendon; Nuclear; containment; design pressure; Construction technology; Anläggningsteknik;

    Sammanfattning : A nuclear power plant is provided with an extensive defense intended to prevent radioactive discharge in case of a reactor accident. This defense is built up of several independent safety barriers, where the reactor containment constitutes the last barrier to the environment. LÄS MER

  3. 3. Vessel wall integrity influence of genetics and flow

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Hanna Björck; Linköpings universitet.; Linköpings universitet.; Linköpings universitet.; [2012]

    Sammanfattning : Cardiovascular disease (CVD) is the major cause of death worldwide. Underlying causes, such as atherosclerosis and hypertension, are associated with remodeling of the vessel wall ultimately leading to loss of structural integrity. There are a number of factors that can influence vascular remodeling and hence structural integrity. LÄS MER

    Sammanfattning : The potentially costly consequences of a lost ship in the form of fatalities, property, cargo and related industries, as well as pollution of the environment in the form of oil spill, etc., and the public view are the driving forces for developing safer ships. Especially RoRo-ferries, i.e. LÄS MER
