    Nyckelord :;

    Sammanfattning : The increased complexity of products and narrow lead times for product development have intensified the use of virtual prototyping, also called simulation-based design. The simulation of each individual manufacturing process is an important part of product development, However it is also necessary to study the complete sequences of manufacturing processes. LÄS MER

  3. 2. Aspects on finite element simulation of sheet metal forming processes

    Författare :Ramin Moshfegh; Kjell Mattiasson; Linköpings universitet; []

    Sammanfattning : This thesis has focused on four different aspects of finite element simulation of sheet metal forming processes. Four substantial research areas are the development of a methodology for predicting the limiting strains in connection with the Forming Limit Diagram, the applicable mode of procedure for finite element simulation of the hydromechanical deep drawing process, the adaptive mesh refinement strategy based on gradients of the effective plastic stresses and strains; and the reliability and sensitivity assessments within sheet metal forming processes.
