The paper is devoted to the theoretical investigation of the peculiarities of material flow taking place in friction stir welding (FSW). The investigation was based on 3D computer simulation by the movable cellular automaton ...

Detailed rigid particle models have been proposed for modeling fracture in quasibrittle materials. The rigid particle circular models proposed in the literature do not properly reproduce the known rock friction angle and ...

Simulation of extrusion processes represents a large challenge for commonly used numerical methods. In our application for example, a hot melt is extruded whilst being rapidly cooled. Under these conditions of quenching, ...

Bulk handling of powders and granular solids is common in many industries and often gives rise to handling difficulties especially when the material exhibits complex cohesive behaviour. For example, high storage stresses ...

In bulk handling applications, such as conveying and storage, understanding the effect cohesion has upon the flow-ability of particulate systems at the macroscopic scale is crucial in increasing the avenues of operation ...

The following paper presents a new approach for the Discrete Element Method (DEM) with polyhedral particles. The geometry of convex polyhedra is represented by a set of half spaces. An algorithm for contact detection for ...

We present PPML, a domain-specific programming language for parallel particle and particle-mesh simulations. PPML provides a concise set of high-level abstractions for particle methods that significantly reduce implementation ...

Phase decomposition and phase separation play important roles in the preparation of precipitation membranes. Phase decomposition is a diffusion–controlled process on a short time scale. Phase separation is a convection–controlled ...

Partitioned approaches for the solution of Fluid-Structure Interaction (FSI) problems are particularly interesting because, among other aspects, they allow for the reuse of existing software. In this work, we propose a ...

Corrective smoothed particle method (CSPM) has been used to study the dynamic behavior of targets with different materials; AL, ALN and AL-ALN FGM in long rod penetration of an AL projectile. A mixed strength model with ...
