in the last decade, decrease of the wear rate, increase in the axel load, and the velocity of the trains have changed the main damage mechanism of railway wheels from wear to rolling contact fatigue (rcf). rcf may lead to surface and subsurface cracks. the interaction between wear and rcf, removes the surface cracks, but the subsurface crack propagate gradually, and may lead to deeper and more ...

Modeling shot peening process is very complex as it involves the interaction of metallic surfaces with a large number of shots of very small diameter. Conventionally such problems are solved using the finite element software (such as ABAQUS) to predict the stresses and strains. However, the number of shots involved and the number of elements required in a real-life components for a 100% coverag...

Engineers from wide ranges of industries face an ever increasing need to run virtual tests to simulate complex models for improving reliability as well as reducing product development time and costs. Abaqus Unified FEA is designed to tackle these challenges by producing high-quality realistic simulation solutions, while delivering high performance in productivity by utilizing efficient use of m...

A 3D finite element model (FEM) for predicting the distribution of lateral pressure in a square flexible walled steel silo during filling phase was analyzed this study. The numerical approach, developed using Abaqus software, predicts stress state bulk solids, as well pressures exerted on walls. An elasto-plastic Drucker–Prager criterion employed to simulate behavior granular materials. FEM sim...

Various experimental studies have been carried out on glass fiber reinforced concrete (GFRC), but in limited studies, the behavior of this type of concrete is evaluated using finite element method (FEM). In this study an analysis model is presented for predicting energy absorption capacity of glass fiber reinforced self-compacting concrete (GFRCSCC) beams and the results are compared with exper...

The scaled boundary finite element method (SBFEM) is capable of generating polyhedral elements with an arbitrary number surfaces. This salient feature significantly alleviates the meshing burden being a bottleneck in analysis pipeline standard (FEM). In this paper, we implement based on SBFEM into commercial software ABAQUS. To end, user are provided through subroutine UEL. Detailed explanation...

This paper presents stress and strain analysis of outer shaft shoulder (OSS) and inner shaft shoulder (ISS) of a new paddy harvesting head (PHH) using finite element method (FEM). Snapping grain unit is a part of this head, with OSS and ISS as its members. The analysis was performed using the ABAQUS software with Dynamics Explicit Solution Method. Eight-node block and four-node tetrahedral elem...

Production of lightweight metals with a higher strength to weight ratio is always the main goal of researchers. In this article, equal channel multi angular pressing (ECMAP) process as one of the most appealing severe plastic deformation (SPD) methods on production of ultra-fine grained (UFG) materials studied. Two main routes A and C investigated by FEM and compared with each other from differ...

The prosthesis - pulsatory ventricular assist device (VAD) - is made of polyurethane (PU) and biocompatible TiN deposited by pulsed laser deposition (PLD) method. The paper discusses the numerical modelling and computer-aided design of such an artificial organ. Two types of VADs: POLVAD and POLVAD_EXT are investigated. The main tasks and assumptions of the computer program developed are present...
