  • Fast FE Analysis system for sheet metal stamping—FASTAMP
    Journal of Materials Processing Technology, 2007
    Co-Authors: Du Ting, Liu Yuqi, Zhang Zhibing, Li Zhigang

    Abstract:

    Abstract FASTAMP is a fast FE Analysis system for sheet metal stamping, which is based on an improved inverse approach and dynamic explicit method. The improved algorithm successfully avoids the strain localization problem existing in plastic deformation theory to lay foundation for the inverse approach. Quadrilateral membrane elements together with DKQ bend element are used in the algorithm to considering bending effect. More accurate model is built in the system so that the process parameters, such as blank-holding force, friction and drawbead restriction, can be taken into account. Press types, eject plate and other influence factors on sheet metal forming are also considered. As a result, the system can be applied to potential defects detection, formability Analysis, Material selection and process verification. Product design, process planning and die design can be integrated by FASTAMP, so that product formability can be ensured, optimization of stamping process and die structure achieved.

  • finite and boundary element linear and nonlinear analyses of shells and shell like structures a bibliography 1999 2001
    Finite Elements in Analysis and Design, 2002
    Co-Authors: Jaroslav Mackerle

    Abstract:

    A bibliography containing references to papers, conference proceedings and theses/dissertations dealing with finite element and boundary element analyses of shells and shell-like structures was presented. The bibliography contained general solution-techniques and problem specific applications. Topics discussed include static and dynamic Analysis of shells, seismic Analysis, impact problems, thermal and thermomechanical Analysis, fracture mechanics, delamination problems, crack Analysis, Material processing, metal forming and adaptive modeling.
