  2. 1. Analysis of transverse cracking in cross-ply laminates: Weibull distribution based approach

    Author : Vivek Richards Pakkam Gabriel; Patrik Fernberg; Mohamed Loukil; Spyros Tsampas; Erik Marklund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intralmainar cracking; Weibull distribution; Failure stress; Monte Carlo simulation; Fatigue loading; Quasi-static loading; Polymera kompositmaterial; Polymeric Composite Materials;

    Abstract : Fiber reinforced polymer composite laminates make up more than 50% of modern aircrafts. Such composite laminates are exposed to various environmental and in-service thermo-mechanical load conditions. READ MORE

  4. 2. Transverse anisotropy in softwoods : Modelling and experiments

    Author : Carl S. Modén; Lars Berglund; Lennart Salmén; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Softwood; Cellular solid; Anisotropy; Deformation mechanisms; Materials science; Teknisk materialvetenskap;

    Abstract : Transverse anisotropy is an important phenomenon of practical and scientific interest. Although the presence of ray tissue explains the high radial modulus in many hardwoods, experimental data in the literature shows that this is not the case for pine. READ MORE

  5. 3. On the Load Distribution and Design of a Chain Drive

    Author : Ingvar Troedsson; Maskinelement; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tension force; tensioner; oscillation; chain drive; vibration; load distribution; Mechanical engineering; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Abstract : Three methods are presented to calculate the load distribution in a chain drive containing two sprockets and one chain. The rollers, which are in contact with the sprockets, can move along the tooth flanks and their positions are given by force equilibrium. READ MORE

  6. 4. Traffic Load Effects on Bridges, Statistical Analysis of Collected and Monte Carlo Simulated Vehicle Data

    Author : Abraham Getachew; KTH; []
    Keywords : bridge; traffic load; transverse distribution; characteristic value; weigh in motion;

    Abstract : Research in the area of bridge design has been and still isconcentrated on the study of the strength of materials andrelatively few studies have been performed on traffic loads andtheir effects. Traffic loads have usually been assumed to begiven in codes. READ MORE

  7. 5. Micromechanics of softwoods in the transverse plane : effects on cell and annual ring scales

    Author : Carl S. Modén; Lars Berglund; Per Johan Gustafsson; KTH; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wood fibre and forest products; Träfiber- och virkeslära; Engineering mechanics; Teknisk mekanik; Biomaterials; Biomaterial;

    Abstract : Transverse mechanical properties of wood are important in many practial applications and an interesting scientific subject. A very low transverse shear modulus has been identified in spruce, which causes large strain concentrations in wood structures. READ MORE
