ABSTRACT Three‐point bending tests were performed on notched specimens extracted from cuboids of 316L stainless steel produced via material extrusion additive manufacturing. The cuboids were printed vertically and horizontally on the printing platform to account for the building orientation effect on the mechanical performance.

A two‐phase volume of fluid approach to model rigid‐perfectly plastic granular materials
A rigid‐perfectly plastic Bingham model is presented, and its implementation into an FV‐VoF procedure is validated for cohesive and noncohesive materials featuring different angles of repose. A close agreement of the predicted soil surface with experimental data is obtained for noncohesive material, and the failure lines, calculated from the introduced

Numerical analysis of downward progressive landslides in long natural slopes with sensitive clay
Landslides occurring in sensitive clay often result in widespread destruction, posing a significant risk to human lives and property due to the substantial decrease in undrained shear strength during deformation.

Abstract The dynamics of fluid flows with free surfaces and interacting with highly deformable structures is a complex problem, attracting considerable attention. The Particle Finite Element Method (PFEM) is one of the various numerical methods recently proposed in the literature to simulate this type of problems. It is a mesh‐based Lagrangian approach,

On the numerical modeling of granular material flows via the Particle Finite Element Method (PFEM)
The aim of this work is to describe a numerical framework for reliably and robustly simulating the different kinematic conditions exhibited by granular materials while spreading ---from a stagnant condition, when the material is at rest, to a transition to granular flow, and back to a deposit profile.

The particle finite element method. An overview
We present a general formulation for analysis of fluid-structure interaction problems using the particle finite element method (PFEM). The key feature of the PFEM is the use of a Lagrangian description to model the motion of nodes (particles) in both the

Modeling of Free Surface Flows with Elastic Bodies Interactions
In this paper, a series of new fluid and structure interactions test cases with strong free surface effects are presented and computations of such flows with the Particle Finite Element Method (PFEM) (Idelsohn, Oiiate, Del Pin and Calvo, 2006) are ...

A Particle Finite Element Method for Machining Simulations
Metal cutting process is a nonlinear dynamic problem that includes geometrical, material, and contact nonlinearities. In this work a Lagrangian finite element approach for simulation of metal cutting processes is presented, based on the so-called ...

Traditionally, discrete element (DE) method and finite element (FE) method are used in numerical simulation of granular flow problems. A drawback with the (DE) method is the limitations in modelling the extreme large number of particles, which normally ...
