   Author : Erik Gustafsson; Niclas Strömberg; Bo Torstenfelt; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Response Surface Methodology RSM ; Residual Stresses; Castings; Engineering mechanics; Teknisk mekanik;

   Abstract : In this thesis structural optimization of castings and thermomechanical analysis of castings are studied.In paper I an optimization algorithm is created by using Matlab. The algorithm is linked to the commercial FE solver Abaqus by using Python script. READ MORE

4. 2. Stress and fatigue constrained topology optimization

   Author : Erik Holmberg; Anders Klarbring; Bo Torstenfelt; Daniel Hilding; Linköpings universitet; []
   Keywords : ;

   Abstract : This thesis concerns structural optimization in conceptual design stages, for which constraints that are adapted to industrial requirements have been developed for topology optimization problems. The objective of the project has been to identify and solve problems that today prevent structural optimization from being used in a broader sense in the avionic industry; the main focus has been on stress and fatigue constraints in topology optimization.

5. 3. Topology optimization considering stress, fatigue and load uncertainties

   Author : Erik Holmberg; Anders Klarbring; Bo Torstenfelt; Pierre Duysinx; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This dissertation concerns structural topology optimization in conceptual design stages. The objective of the project has been to identify and solve problems that prevent structural topology optimization from being used in a broader sense in the avionic industry; therefore the main focus has been on stress and fatigue constraints and robustness with respect to load uncertainties.

6. 4. Developments of Topology Optimization Methods for Additive Manufacturing involving High-cycle Fatigue

   Author : Shyam Suresh; Anders Klarbring; Stefan Lindström; Carl-Johan Thore; Bo Torstenfelt; Mathias Wallin; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Additive manufacturing (AM) is a versatile manufacturing process which is gaining popularity in the automotive and aerospace industries. Through AM one can manufacture complex structures and combined with topology optimization (TO) a powerful design tool that provides great freedom in geometric form emerges. READ MORE

7. 5. Topology Optimization for Additive Manufacturing Involving High-Cycle Fatigue

   Author : Shyam Suresh; Anders Klarbring; Stefan B Lindström; Carl-Johan Thore; Bo Torstenfelt; Reijo Kouhia; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Additive Manufacturing (AM) is gaining popularity in aerospace and automotive industries. This is a versatile manufacturing process, where highly complex structures are fabricated and together with topology optimization, a powerful design tool, it shares the property of providing a very large freedom in geometrical form.
