1. 1. Optimisation of Machining Operations by means of Finite Element Method and Tailored Experiments

   Författare :Amir Malakizadi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Usui wear model; Bi-metals; Flank wear; Johnson-Cook; Inverse identification; Metal cutting; Thermal fatigue cracking; Wear modelling; Finite element method; Response surface methodology;

   Sammanfattning : Traditionally, costly experimental procedures have been followed in industry to optimise the machining operations to secure the maximum efficiency in production line, while the functional requirements of the machined surfaces are fulfilled. In recent years, development of robust numerical techniques such as Finite Element Method (FEM) and advances in computing capacity of computers have made it possible to simulate the machining operations under operational conditions.

3. 2. Optimisation of Machining Operations by means of Finite Element Method and Tailored Experiments

   Författare :Amir Malakizadi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Response Surface Methodology; inverse identification; bi-metals; flank wear; Wear modelling; thermal fatigue cracking; Finite Element Method; Usui’s model; metal cutting; Johnson-Cook;

   Sammanfattning : The experimental approach has long been the main method to investigate the responses associated with metal cutting process such as cutting forces and temperatures and also to optimise the machining operations to accomplish higher productivity. In recent years, with advances in computing power of computers along with development of robust numerical methods such as Finite Element Method (FEM), it has been possible to simulate different machining process under operational conditions.

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

   Författare :Md Shafiqul Islam; Sharon Kao-Walter; Christian Johansson Askling; Martin Kroon; Blekinge Tekniska Högskola; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

   Sammanfattning : To increase the competitiveness of the Swedish aero engine industry alternative manufacturing methods for load carrying aero engine structures are desired, in order to reduce product cost and enable weight reduction and thereby fuel consumption. Traditionally, these structures mainly consist of large-scaled single castings of e.g. LÄS MER
