  1. 1. Cohesive modelling of the temperature dependence of epoxy based adhesives in Mode I and Mode II loading

    Författare :Tomas Walander; Ulf Stigh; Anders Biel; Erik Serrano; Högskolan i Skövde; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Cohesive laws; Epoxy adhesive; Fracture energy; Peak stress; Temperature; Regression analyses; Shear modulus; Young’s modulus.; Teknik; Technology;

    Sammanfattning : In this work, the influence of the temperature on the cohesive laws for two epoxy adhesives is studied at temperatures below the glass transition temperature for both Mode I and Mode II loading. Cohesive laws are measured experimentally under quasi-static loading conditions in the temperature range -30≤T≤80"C" . LÄS MER

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

    Författare :Tomas Walander; Christian Berggreen; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; mixed mode; temperature; multi-axial fatigue; finite element analysis; fatigue; cohesive law; adhesive layer; fracture energy; potential model; 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
