Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020 In this paper, we develop a new computational framework to investigate the sloshing free surface flow of Newtonian and non‐Newtonian fluids in the rectangular tanks. We simulate the flow via a two‐phase model and employ the fixed unstructured mesh in the computation to avoid the mesh distortion and reconstruction.

Procedia CIRP, 2013 The (PFEM) is employed to simulate orthogonal metal cutting of 42CD4 steel. The objectives of this work are mainly three: The first one is to validate PFEM strategies as an efficient tool for numerical simulation of metal cutting processes by a detailed comparison (forces, stresses, strains, temperature, etc.) with results provided by commercial finite

Enhanced cone penetration test interpretation with the Particle Finite Element Method (PFEM)
, 2019 The paper presents an enhanced interpretation of the cone penetration test based on numerical analysis performed using the Particle Finite Element Method (PFEM). This method allows the incorporation of strong non-linearities, notably those associated with the large displacements and strains arising from the process of the penetration of the cone ...
