  3. 17. Comprehensive numerical analysis of stress state in adhesive layer of joint including thermal residual stress and material non-linearity

    Författare :Nawres Jabar Al-Ramahi; Roberts Joffe; Janis Varna; Lars Mikkelsen; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Single-lap adhesive joint; Double-lap adhesive joint; Unbalanced bi-material DCB; Residual thermal stresses; Finite element method; Crack path; Crack closure; Polymeric Composite Materials; Polymera kompositmaterial;

    Sammanfattning : The main objective of this work is to improve understanding of the stress state in the adhesive layer of bonded joints and identify key parameters which govern performance of adhesive joints. This information is crucial for the prediction of the failure initiation and propagation with the further estimation of the durability and strength of adhesively bonded structures. LÄS MER

    Sammanfattning : Mechanical Behaviour of Adhesive Layers Methods to Extract Peel and Mixed Mode Properties TOBIAS ANDERSSON Department of Applied Mechanics Chalmers University of Technology ABSTRACT This thesis is concerned with methods to extract material properties of thin adhesive layers loaded in peel and in mixed mode. The first part of the thesis is devoted to an experimental method to determine the complete stress-elongation relation (or cohesive law) for an adhesive layer loaded in peel using the DCB-specimen.

  5. 19. Steel members strengthened with carbon fibre reinforced polymers - A study of local and global structural behaviour

    Författare :Dag Linghoff; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforcement; CFRP laminate; adhesive; design;

    Sammanfattning : Investigations have been conducted by several research groups to study the effect of using carbon fibre reinforced polymers (CFRP) as reinforcement on steel beams and a brief summary of this work is given in this thesis. Laboratory studies of reinforced steel beams demonstrate that the bending stiffness and the ultimate load-carrying capacity can be significantly increased. LÄS MER

  7. 20. Functional Layer-by-Layer films and aerogels of cellulose nanofibrils

    Författare :Erdem Karabulut; Lars Wågberg; Joseph B. Schlenoff; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis deals with the preparation of functional Layer-by-Layer (LbL) films of cellulose nanofibrils (CNFs) and polyelectrolytes. LbL films ranging in thickness from 10 nm to 5 μm were deposited onto both solid surfaces and porous nanocellulose aerogels in order to prepare functional surfaces and materials. LÄS MER
