  • Moving particle Finite Element Method with global smoothness
    International Journal for Numerical Methods in Engineering, 2004
    Co-Authors: Su Hao, Kam Liu, Ted Belytschko
    Abstract:

    We describe a new version of the moving particle Finite Element Method (MPFEM) that provides solutions within a C0 Finite Element framework. The Finite Elements determine the weighting for the moving partition of unity. A concept of ‘General Shape Function’ is proposed which extends regular Finite Element shape functions to a larger domain. These are combined with Shepard functions to obtain a smooth approximation. The Moving Particle Finite Element Method combines desirable features of Finite Element and meshfree Methods. The proposed approach, in fact, can be interpreted as a ‘moving partition of unity Finite Element Method’ or ‘moving kernel Finite Element Method’. This Method possesses the robustness and efficiency of the C0 Finite Element Method while providing at least C1 continuity. Copyright © 2004 John Wiley & Sons, Ltd.

  • Moving particle Finite Element Method
    International Journal for Numerical Methods in Engineering, 2002
    Co-Authors: Harold S. Park
    Abstract:

    This paper presents the fundamental concepts behind the moving particle Finite Element Method, which combines salient features of Finite Element and meshfree Methods. The proposed Method alleviates certain problems that plague meshfree techniques, such as essential boundary condition enforcement and the use of a separate background mesh to integrate the weak form. The Method is illustrated via two-dimensional linear elastic problems. Numerical examples are provided to show the capability of the Method in benchmark problems.
