2. 1. 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 : 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

4. 2. FE-Simulation of Metal Cutting Processes

   Author : Ahmet Semih Ertürk; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metal cutting; Ductile fracture; Gradient damage; Finite element method; Turning; Machining; Inverse identification;

   Abstract : This thesis deals with the finite element (FE) simulation of machining processes. Realistic simulation of metal cutting processes enables a more resource-efficient machinability assessment for a given material in terms of cutting forces, chip shape and tool wear at different ranges of cutting conditions.

5. 3. Modeling of cast iron materials related to machining

   Author : Goran Ljustina; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining simulation; Microstructure; Fracture; Johnson Cook plasticity;

   Abstract : A microstructure level simulation model of cast iron machining based on micrograph image analysis has been developed. The simulation tool has been developed for theorthogonal machining process involving 2D representations of a range of cast iron microstructures. READ MORE

6. 4. Impact Simulation of Adhesively Joined Structures

   Author : Thomas Carlberger; Högskolan i Skövde; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesive joining; Dynamic fracture; Cohesive zone; Interphase Element; Bi-material joining; Engineering mechanics; Teknisk mekanik; Teknik; Technology;

   Abstract : The development of competitive and crashworthy automotive car bodies has reached so far that the manufacturers no longer rely on mono-material steel structures. Improved strength/weight performance may be achieved by using optimal material in each part of the car structure, leading to bi-material joints and ruling out spot welding; the common joining method during the past half century of automotive history.
