  2. 16. Wood Plastic Composites made from Modified Wood : Aspects on Moisture Sorption, Micromorphology and Durability

    Author : Kristoffer Segerholm; Ove Söderström; Magnus Wålinder; Mats Westin; Pia Larsson Brelid; Per Johan Gustafsson; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wood plastic composites; WPC; acetylation; heat treatment; furfurylation; moisture sorption; micromorphology; decay; UV laser; soil test; Biomaterials; Biomaterial;

    Abstract : Wood plastic composite (WPC) materials have seen a continuous market growth worldwide in the last decade. So-called extruded WPC profiles are today mainly used in outdoor applications, e.g. decking, railing and fencing. READ MORE

  4. 17. Plastic Shrinkage Cracking in Concrete

    Author : Faez Sayahi; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : Early-age (up to 24 hours after casting) cracking may become problematic in any concrete structure. It can damage the aesthetics of the concrete member and decrease the durability and serviceability by facilitating the ingress of harmful material. READ MORE

  5. 18. Plastic Shrinkage Cracking In Concrete : Mitigation and Modelling

    Author : Faez Sayahi; Mats Emborg; Andrzej Cwirzen; Hans Hedlund; Pietro Lura; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : Early-age (up to 24 hours after casting) cracking may become problematic in any concrete structure. It can have a negative influence on the aesthetics of the concrete structure, as well as decreasing the durability and serviceability by facilitating the ingress of harmful materials into the concrete bulk.

  6. 19. Monotonic and Cyclic Plastic Deformation of High-Strength Aluminium Alloys

    Author : Magnus Hörnqvist Colliander; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strain rate effects; Heat treatment; Dynamic strain ageing; Precipitation hardening; Low cycle fatigue; AA7030; Plastic deformation; Temperature effects; EN AW-7030; Al-Zn-Mg; Strain hardening; Mechanical properties; Dynamic precipitation.;

    Abstract : Dynamic strain ageing (DSA) and dynamic precipitation (DP) are two, closely interrelated, phenomena arising from the dynamic interaction between mobile solute atoms and dislocations. The occurrence of DSA and DP is confined to specific ranges of strain rate and temperature, and aluminium alloys are generally prone to experience DSA and DP already at ambient temperatures and conventional strainrates.

  7. 20. Modeling the behavior of inclusions in plastic deformation of steels

    Author : Chunhui Luo; KTH; []
    Keywords : Inclusion; Steel; Plastic deformation; Void; Rolling; Forging; Finite element; Mesomechanical approach;

    Abstract : This doctoral thesis presents a modeling method fordemonstrating the behavior of inclusions and their surroundingmatrix during plastic deformation of steels.Inclusions are inescapable components of all steels. READ MORE
