A mixed u–p edge-based smoothed particle finite element formulation for viscous flow simulations

Abstract A mixed u–p edge-based smoothed particle finite element formulation is proposed for computational simulations of viscous flow. In order to improve the accuracy standard method, and face-based smoothing operations on displacement gradient are 2D 3D analyses, respectively. Consequently, spatial integration involving operator performed domains. The constitutive model based an elasto-viscoplastic allowing fluid or fluid-like solid materials. response modeled using overstress function. performance method (ES-PFEM) demonstrated by several numerical benchmark studies, showing excellent agreement with analytical reference solutions improved efficiency in comparison results from PFEM model. Finally, a application ES-PFEM simulation extrusion process during 3D-concrete-printing discussed.
