  5. 3. Smoothing and adaptive remeshing schemes for graded element

    Author : Seokjeong Hyun; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : The objective of the present work is to develop mesh smoothing and adaptive remeshing schemes to improve the Finite Element Analysis. Smoothing and adaptive remeshing techniques are studied for graded element. Different smoothing techniques are implemented and shown. READ MORE

  6. 4. Adaptive remeshing and simulating a chain of manufacturing process

    Author : Seokjeong Hyun; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : Simulations of manufacturing process do in general need adaptive meshing techniques. These can not only make it possible to obtain the solution more efficient but they can also be necessary to enable a solution to be obtained at all. The latter is the case for processes like forging where very large deformations occur. READ MORE

  7. 5. Simulation of mechanical cutting

    Author : Vahid Kalhori; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : This thesis deals with simulation of mechanical cutting. It focuses on orthogonal cutting. Thus it is possible to use two-dimensional models. The strong thermo-mechanical coupling must be accounted for in the model. READ MORE
