We present a novel slanted faces of thin-disk composite Yb:YAG YAG laser which is side-pumped by four non-symmetric hollow- ducts. The pump light distribution in the disk is modeled by using Monte-Carlo ray tracing method. The temperature distribution inside the crystal is calculated by taking into account either the concentration of Yb+3 ion or the different transmission of laser output coupl...

A photogrammetric method of stress analysis has been developed to test thin, nonstandard windows designed for hydrogen absorbers, major components of a muon cooling channel. The purpose of the absorber window tests is to demonstrate an understanding of the window behavior and strength as a function of applied pressure. This is done by comparing the deformation of the window, measured via photog...

The design software system described here is based on a combination of several software components. These components include optimization, physics-based analysis such as computational fluid dynamics (CFD) and finite element analysis (FEA) and supporting tools, and shape design parameterization. The optimization and CFD/FEA related codes, such as mesh generation and partitioning, can be consider...

In this paper, a review of some techniques proposed in the literature for modelling fretting wear is presented. Fretting wear occurs when surfaces are degraded and materials are removed due to a small relative oscillatory motion between two contact surfaces. Due to the continuous change in the shape of a structure during its lifetime, the design of engineering components subjected to fretting w...

The overall goal of my work is to gain insight into how tooth shape relates to its function. As a step towards this, I undertook an independent study project to learn finite element analysis (FEA) this semester, and to lay a foundation for my future Master’s thesis project work. After solving a series of problems on paper, reading through my supervisor’s work, and referring to a range of papers...

This research work aims to analyse isotropic triangular mild steel plate constrained by boundary condition using Finite Element Analysis with CST as master element. Static deformation analysis of a mild steel triangular plate fixed at one end under point loads at the free end has been performed using Constant Strain Triangle (CST) as finite element. FEA analysis techniques are used to find the ...

This paper presents a new method for the signature analysis of mechanical watch movements. Contrary to the existing method, it analyzes the time-frequency features of mechanical watch movement through a combination of reassigned scalogram and Finite Element Analysis (FEA). By mapping the signal into a 2D domain of time and frequency, the reassigned scalogram reveals the frequency components of ...

This paper presents an eddy current loss analysis for a transverse flux rotary machine (TFRM) with laminated stator cores, which consist of inner and outer cores whose laminated directions are perpendicular to each other. Although the TFRM is laminated to reduce eddy current losses, it still exhibits rapidly increasing core losses as the frequency increases. To solve this problem, slits are int...
