One of the major problems in experimental vibration analysis is to determine location of transducers. It is important to place the transducers on locations with largest vibration amplitude and to avoid locations with zero-movement (nodal lines). These locations are best seen from vibration mode shapes. Finite element analysis (FEA) provides numerical values for natural frequencies, which are so...

Silicon wafers are used as substrates to build more than 90% of integrated circuits. One of the manufacturing processes for silicon wafers is grinding. This paper reports the investigations of silicon wafer grinding using Finite Element Analysis (FEA). FEA models are first used to study the effects of process parameters on waviness reduction in the grinding of wire-sawn wafers on a rigid chuck....

Prevailing assumptions made in the published finite element analysis (FE...

The inception voltage of the positive corona discharges (CIV) in a typical wire-cylinder electrode arrangement in air, under high voltage dc application, has been studied by implementing the Finite Element Analysis (FEA). Numerical analysis has been carried out on the electric field intensity, along the wire-cylinder gap axis, in order to determine the inception voltage of each air gap and defi...

A set of input specifications is designed to enable engineers and scientists, who may not be computer experts, to describe the finite element analysis (FEA) procedures for a new application. The input directs PIER, a code derivation/generation system being developed in Common Lisp, to produce either sequential or parallel FEA codes. The PIER input employs common terminology and notations as use...

Beams are high-aspect-ratio structural members that are used extensively in civil, automotive, aerospace, and MEMS applications. In all such applications, one must typically analyze and optimize the beams through computer simulations. Standard 3-D finite element analysis (FEA) of beams can be used in such simulations; it is however prone to errors, and is computationally expensive for thin stru...

Numerical analysis of Partial Differential Equations (PDE's) of the solid mechanics using Finite Element Method (FEM) is very popular. One issue which is haunting the finite element solution is the computer time. Finite Element Analysis (FEA) using fine mesh and large number of nodes consumes lot of solution time. To overcome this difficulty, a hybrid Neuro-FEM is proposed. FEM solutions consid...

This paper covers numerical investigations of the draping of woven fabrics into a “hat” shape, combining a hemispherical cup with a wide flat rim. A mechanical approach is adopted using finite element analysis (FEA) methodology. In this, the fabric is considered as a solid sheet with mechanical properties and friction properties. In this study, a linear elastic anisotropic material model descri...

A mathematical model for the flow of human blood through an artery bifurcation is studied using finite element analysis (FEA). The FEA has been applied for a two-dimensional steady flow of an in-viscous fluid through different geometries. The flow through a two-dimensional model of a carotid artery bifurcation has been simulated. The velocity profiles through the bifurcation branches were compu...

A Finite Element Analysis (FEA) system was designed for the analysis of creep deformation and damage evolution in weldment. This project essentially consists of three parts which involves 1) transfer programme development, 2) numerical integration subroutine development, and 3) validation of complete FEA system. Firstly, the development of a user-friendly preand postprocessing transfer programm...
