  1. 1. Evaluation of cracks in corrugated board, Evaluating cracks using Finite Element Method and J-integral

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Ming-Yang Li; [2021]
    Nyckelord :corrugated board; corrugated box; finite element method; fracture mechanics; mechanical properties; wellpapp; finita elementmetoden; frakturmekanik; mekaniska egenskaper;

    Sammanfattning : This report investigates whether a FEM model can be used to assess the risk of crack growth in corrugated board. A set of box geometries with cracks at different locations were loaded and then compared using the evaluated J-integral within the FEM software. LÄS MER

  3. 2. Adhesive modelling in multi-material structures : Evaluating the strength and fatigue life of adhesive joints

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Nitin Narayanaswamy; [2020]
    Nyckelord :Adhesive Joints Strength Calculation J Integral Method Energy Release Rate Theory Crack Finite Element Analysis Multi Material Structures Automotive;

    Sammanfattning : Advancements in material science and manufacturing techniques are enabling the use of lightweight metal alloys and polymer composites in several combinations and shapes for producing more efficient and lightweight structures for automotive applications without compromising strength, stiffness and/or durability. When evaluating the strength of the structure, the joints are of importance. LÄS MER

  4. 3. Virtual Material Testing of Adhesive Joints

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Vinit Jethalal Nagda; [2020]
    Nyckelord :;

    Sammanfattning : The automotive industry has shown an increasing interest in adhesive bonding for mixed-material joining. Modern design methods are critically dependent on accurate material models and data for numerical methods to enable the simulation of a design prototype early in the design process. LÄS MER

  5. 4. Additive weld manufacturing and material properties effect on structural margins

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Daniel Arvidsson; [2018]
    Nyckelord :;

    Sammanfattning : the FE analyses. Traditionally all parts are modeled with isotropic base material. Analyses are made on a part of the nozzle which includes both a butt weld and metal deposition and which is an interface to another part causing loads that has to be sustained by the weld and the MD.

  7. 5. Determination of fracture mechanics behavior of polyethylene sheets

    Magister-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Min Jin; [2017]
    Nyckelord :Material behavior; Fracture mechanics; Elastic plastic fracture mechanics; J-Integral; Numerical analysis; ABAQUS;

    Sammanfattning : Polyethylene is a widely-used material in package industries. The fracture behavior of this material has not been studied in the plastic region in many years. In this thesis work, the J-Integral which is one material property used to represent the plastic material strength is calculated through the numerical analysis. LÄS MER
