  2. 1. Microstructure-based Mechanical Behaviour in Structural Analyses of Cast Components

    Author : Jakob Olofsson; Ingvar L. Svensson; Salem Seifeddine; Torsten Sjögren; Jönköping University; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Component behaviour; Structural analysis; Mechanical behaviour; Casting process simulation; Finite element method simulation;

    Abstract : In the process of developing cast iron and cast aluminium components, the co-operation between product development and production is important. On the engineering level, this co-operation is limited already in the product development phase e.g. by the lack of established methods to consider the mechanical behaviour of the completed component.

    Abstract : In the process of developing cast iron and cast aluminium components, a high level of co-operation between product development and production is of great importance. From an engineering standpoint, this co-operation is limited early in the product development phase by e.g. READ MORE

  5. 3. Fracture and Delamination in Packaging Materials : A Study of Experimental Methods and Simulation Techniques

    Author : Md Shafiqul Islam; Sharon Kao-Walter; Christian Johansson Askling; Martin Kroon; Blekinge Tekniska Högskola; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; packaging materials and laminates; shear test specimen; essential work of fracture; finite element simulation; optimization; tearing; peel; polymers; cohesive zone modelling;

    Abstract : Packages are the means of preservation, distribution and convenience of use for food, medicine and other consumer products. The introduction of a new package-opening technique for a better opening experience requires additional prototype development and physical testing. READ MORE

  6. 4. Non-Linear Vibration and Dynamic Fracture Mechanics of Bridge Cables

    Author : Armando Leon; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cable Vibrations; Non-Linear Vibration; Dynamic Fracture Mechanics; Cable-Stayed Bridges; Dynamic Stress Intensity Factor;

    Abstract : In the present work, the non-linear vibrations and the corresponding dynamic fracture mechanics of cables of cable-stayed bridges are studied. The cables are among the most critical components in cable-stayed bridges and there are different damage sources such as corrosion, vibration, fatigue and fretting fatigue that can significantly affect them, thereby reducing the cable’s service life and even producing their failure.

    Abstract : This thesis focuses on the effect of microstructural variation on the mechanical properties and deformation behavior of ductile iron. To research and determine these effects, two grades of ductile iron, (i) GJS-500-7 and (ii) high silicon GJS-500-14, were cast in a geometry containing several plates with different section thicknesses in order to produce microstructural variation.
