This paper presents a novel method for prediction of the mechanical behavior of proximal femur using the general framework of the quantitative computed tomography (QCT)-based finite element Analysis (FEA). A systematic imaging and modeling procedure was developed for reliable correspondence between the QCT-based FEA and the in-vitro mechanical testing. A speciallydesigned holding frame was used...
This paper describes a prototype implementation of an online data access system for a finite element analysis (FEA) program. The system incorporates a commercial off-the-shelf (COTS) database as the backend to store selected analysis results; and the Internet is utilized as a data delivery vehicle. The objective is to provide the users an easy-to-use mechanism to access the needed analysis resu...
Traditional finite element analysis (FEA) programs are typically built as standalone desktop software. This paper describes an Internet-enabled framework that facilitates building a FEA program as distributed web services. The framework allows users easy access to the FEA core service and the analysis results by using a web-browser or other application programs. In addition, the framework enabl...
A characterization of the rotor losses in single-sided axialflux permanent-magnet (AFPM) machines fitted with nonoverlapped windings (NOW) is presented in this paper, through experimental validation of finite element analysis (FEA) estimates. A literature review detailing the previous work done in the area of rotor loss estimation is given and the approaches taken by the authors to model the AF...
Since torque ripple is the main cause of noise and vibrations, the performance of Switched Reluctance Motor (SRM) can be improved by minimizing its torque ripple using a novel control technique called Direct Torque Control (DTC). In DTC technique, torque is controlled directly through control of magnitude of the flux and change in speed of the stator flux vector. The flux and torque are maintai...
Abstract A Problem Solving Environment for the finite element method (FEM-PSE) is an application system to support users pursuing a career in the finite element analysis (FEA). There are two types of users associated with the FEA. One is analysis-user who uses application software of the FEM and the other is development-user who develops application software of the FEM. We used an abstraction t...

In semiconductor packaging, warpage is one of the critical issues during molding stage. It is related to a thermal mismatch i.e. coefficient of thermal expansion (CTE) values and reliability of passive components in the package. Finite element method (FEM) is able to perform extensive structural analysis of quad flat no-lead (QFN) package designs once verified by experiments. 2 factorial is emp...
