Axial Flux Permanent Magnet (AFPM) machines are attractive candidates for Electric Vehicles (EVs) applications due to their axial compact structure, high efficiency, high power and torque density. This paper presents general design characteristics of AFPM machines. Moreover, torque density of the machine which is selected as main objective function, is enhanced by using Genetic Algorithm (GA) a...

BACKGROUND Three-dimensional finite element analysis (FEA) is effective in analyzing stress distributions around dental implants. However, FEA of living tissue involves many conditions, and the structures and behaviors are complex; thus, it is difficult to ensure the validity of the results. To verify reproducibility and validity, we embedded implants in experimental models and constructed FEA ...

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...

In this paper a brushless permanent magnet motor is designed considering minimum thrust ripple and maximum thrust density (the ratio of the thrust to permanent magnet volumes). Particle Swarm Optimization (PSO) is used as optimization method. Finite element analysis (FEA) is carried out base on the optimized and conventional geometric dimensions of the motor. The results of the FEA deal to ...

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....

BACKGROUND The optimal treatment of flat epithelial atypia (FEA) found on breast core needle biopsy (CNB) is controversial. We performed a retrospective review of our institutional experience with FEA to determine if excisional biopsy may be deferred. METHODS Surgical records from 2009 to 2012 were reviewed for FEA diagnosis. After exclusion for concomitant lesions, CNBs of pure FEA were clas...

Bearing designers have expanded their use of advanced Finite Element Method (FEM) as a result of improvements in computer hardware and software. Automotive bearing designers increasingly apply Finite Element Analysis (FEA) to the design of integrated automotive bearing products which tend to evolve gradually into sophisticated components. FEA is an effective tool that enables NSK to develop and...

Motion-analysis and FEA can work together even though they are quite different. Motion-analysis software works with CAD assemblies. It starts by translating assembly mating conditions into corresponding kinematics pairs. It then calculates kinematics and dynamics data of the moving mechanism. Each component in mechanism, if viewed separately, is under balanced set of loads: joint reactions and ...

BACKGROUND Finite element analysis (FEA) of the proximal femur has been previously validated with large mesh size, but these were insufficient to simulate the model with small implants in recent studies. This study aimed to validate the proximal femoral computed tomography (CT)-based specimen-specific FEA model with smaller mesh size using fresh frozen cadavers. METHODS Twenty proximal femora...

Artificial Intelligence (AI) approaches to Finite Element Analysis (FEA), have had tentative degrees of success over the last few years and some authors have argued that effective FEA can help in the manufacture reliability and safety aspects of engineered artefacts. The author of this paper reviews how such AI techniques have been applied and in this light, the author then uses a Fuzzy Cogniti...
