1. 1. Mixed mode loaded adhesive layers : from measurement of material data to analysis of structural behaviour

   Författare :Jia Li Högberg; Högskolan i Skövde; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesive layer; mixed mode testing; cohesive law; J-integral; Engineering mechanics; Teknisk mekanik; Teknik; Technology;

   Sammanfattning : In manufacturing of multi-material products, a joining method that is able to cost-effectively assemble components made of dissimilar and similar material, with irregular geometries, is optimal. As an alternative, adhesive bonding is in-creasingly adapted by the industry, which is also used in manufacturing of multi-phase materials. LÄS MER

3. 2. Influences of temperature, fatigue and mixed mode loading on the cohesive properties of adhesive layers

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesive layer; cohesive law; fatigue; finite element analysis; fracture energy; mixed mode; multi-axial fatigue; potential model; temperature; Mechanics of Materials; Materialmekanik;

   Sammanfattning : This thesis concerns some aspects that have influence on the strength of adhesive layers. The strength is determined by the stress deformation-relation of the layer. This relation is also referred to as cohesive law. LÄS MER

4. 3. Growth of fatigue cracks subjected to non-proportional Mode I and II

   Författare :Peter Dahlin; Mårten Olsson; Veronique École; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue crack growth; Mode II overloading; Crack closure; Sequential mixed mode loading; Other engineering mechanics; Övrig teknisk mekanik;

   Sammanfattning : This thesis deals with some aspects of crack growth in the presence of cyclic loading, i.e. fatigue. The cyclic load cases studied here are primary of non-proportional mixed mode type. LÄS MER

5. 4. Mechanical Behaviour of Adhesive Layers : Methods to Extract Peel and Mixed Mode Properties

   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.

7. 5. Source Language of Lexical Transfer in Multilingual Learners : A Mixed Methods Approach

   Författare :Hannah Neuser; Maria Kuteeva; Philip Shaw; Camilla Bardel; Scott Jarvis; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; multilingualism; third language acquisition; lexical transfer; crosslinguistic influence; modal differences; proficiency; recency; exposure; psychotypology; L2 status; transferability; markedness; lexical organization; activation; lexical access; English; engelska;

   Sammanfattning : The study reported in this thesis investigates the source language of lexical transfer in multilingual learners using a mixed methods approach. Previous research has shown that the source language of crosslinguistic influence can be related to factors such as proficiency, recency/exposure, psychotypology, the L2 status, and item-specific transferability.
