The main purpose of this work is the computational simulation of the sensitivity coefficients of the homogenized tensor for a polymer filled with rubber particles with respect to the material parameters of the constituents. The Representative Volume Element (RVE) of this composite contains a single spherical particle, and the composite components are treated as homogeneous isotropic media, resu...

This paper presents a study the effect of nose radius (Rz-mm) on cutting force components and temperatures during the machining simulation in an orthogonal cutting process for titanium alloy (Ti-6Al-4V). The cutting process was performed at various nose radiuses (Rz-mm) while the depth of cut (d-mm), feed rate (fmm/tooth) and cutting speed (vc-m/ min) were remained constant. The main cutting fo...

The classical finite element method has been successfully applied to many engineering problems but not cases with space discontinuity. A peridynamics-based (PeriFEM) is presented according the principle of minimum potential energy, which enables First, integral domain peridynamics reconstructed, and a new type called peridynamic (PE) defined. Although PEs are generated by continuous elements (C...

Time-of-flight diffraction method (ToFD) is an amplitude-independent sizing method which is based on the measurement of time-of-flight of defect tip diffracted waves. Although ToFD can measure through-wall length of defect accurately, this method is not capable of measuring horizontal defect size. In this paper, a new ToFD method for evaluating horizontal planar defects is presented. The finite...

There are emerging demonstrations that microor nano-craters engineered on polymer surfaces can enable enhanced adhesion. In the past, we have developed a framework for quantifying the suction forces produced by isolated macroscopic craters neglecting surface effects. In this paper, we take surface tension into consideration because it plays a significant role in miniature craters on soft polyme...

ISSN 2277 – 5056 | © 2012 Bonfring Abstract--A FEM simulation study was carried out to investigate the influence of the rolling parameters on the rolling process. Using commercial FEM software, ABAQUS, a number of cases were studied. In this paper, a twodimensional Elastic-plastic finite element model to simulate the cold rolling of thick strip with different roll angular velocity and roll diam...

Three-point bend fracture tests have been conducted at different loading rates with a quadratic martensitic steel. The failure energy has found to increase rate. To get insights in this numerical investigation undertaken strategies using ABAQUS and IMPETUS softwares order address quasi-static dynamic conditions. Simulations were the software carry out comparative analysis of both implicit expli...

In the present study, fatigue behavior and tensile strength of A6061-T4 aluminum alloy, joined by friction stir spot welding (FSSW), are numerically investigated. The 3D finite element model (FEM) is used to analyze FSSW joint means Abaqus software. determined for joints with both a probe hole refilled hole. order calculate life joints, hysteresis loop first determined, then plastic strain ampl...

Rock bursts are a natural phenomenon that caused by high stresses and faults within the deep geological profile. The framework mining excavations, comprising various rock face supports such as cable bolts, is required to withstand bursts. These mechanisms subject static dynamic loading conditions which possess unique challenges. This study focused on shearing impact of loads key structural supp...
