In the present study, the survey of research work on finite element analysis of metal forming processes has been carried out. A classification of formulations dealing with geometry and material nonlinearity in the context of finite element simulation of f... see more

An adaptive mixed finite element method using the Lagrange multiplier technique is used to solve elliptic problems with delta Dirac source terms. The problem arises in the use of Chow-Anderssen linear functional methodology to recover coefficients locally... see more

A meshless local Petrov-Galerkin (MLPG) method that employs polygonal sub-domains constructed from several triangular patches rather than the typically used circular sub-domains is presented. Moving least-squares approximation is used to construct the tri... see more

Large eddy simulation of turbulent channel flow is carried out at Ret values of 150 and 395. Mesh refinement effects are evaluated on conventional meshes, then local mesh refinement in streamwise direction is applied and investigated. The goal of the pape... see more

Advection errors are common in basic terrain-following (TF) coordinates. Numerous methods, including the hybrid TF coordinate and smoothing vertical layers, have been proposed to reduce the advection errors. Advection errors are affected by the directions... see more

Weak local residual (WLR) detects the smoothness of numerical solutionsto conservation laws. In this paper we consider balance laws with a sourceterm, the shallow water equations (SWE). WLR is used as the re?nement indicatorin an adaptive ?nite volume met... see more

WiMAX is a new wireless metropolitan area networks technology based on IEEE 802.16 standard. WiMAX can provide high-speed connection for Internet. IEEE 802.16 standard is an open broadband wireless access technology, which supports high data rate and mult... see more

In this study, finite element simulation of tube extrusion process has been carried outconsidering different mesh adaptivity schemes. A comparison of these schemes has been madebased on stress, strain distribution, and load-stroke curves. Based on the fin... see more

A pneumatic gas gun has been used to fire ogive-nosed projectiles on aluminium plates(1mm) at varying impact velocities above the ballistic limit. Impact and residual velocities havebeen measured. Deformation of the target plate was studied. Experimental ... see more
