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

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

13. High Order Symmetric Finite Difference Schemes for the Acoustic Wave Equation
Sammanfattning : When someone speaks, or when a piano is played, sound waves are spread through the room. Physically the propagation of sound is governed by the acoustic wave equation. This thesis deals with the problem of finding solutions to this equation by numerical methods. LÄS MER
14. Finite Element Procedures in Modelling the Dynamic Properties of Rubber
Sammanfattning : Rubber is not only a non-linear elastic material, it is also dependent on strain rate, temperature and strain amplitude. The non-linear elastic property and the strain amplitude dependence give a non-linear dynamic behavior that is covered by the models suggested in this thesis. LÄS MER
15. Demagnetization Studies on Permanent Magnets : Comparing FEM Simulations with Experiments
Sammanfattning : In a world where money often is the main controlling factor, everything that can be tends to be more and more optimized. Regarding electrical machines, developers have always had the goal to make them better. LÄS MER
