Thesis (MScEng (Mechanical and Mechatronic Engineering))--University of Stellenbosch, 2009.<br>ENGLISH ABSTRACT: In the primary circuit components of high temperature reactors, various unwanted particles have been found. These particles include, for example, graphite and silver- 110 (110mAg). The silver-110 (110mAg) particles are radioactive, with a half-life of 253 days. The presence of radioactive particles in the primary circuit components constitutes an unwanted maintenance problem from a radiation hazard point of view. The development of a method to remove these particles from the he

A solution procedure based on the finite strip method is presented herein, for the analysis of plate systems exhibiting geometric and material non-linearities. Special emphasis is given to the particular problem of rectangular plates with stiffeners running in a direction parallel to one side of the plate. The finite strip method is selected for the analysis as the geometry of the problem is well suited for the application of this method and also as the problem is too complicated to solve analytically. Large deflection effects are included in the present study, by taking first, order non-line

Various models are currently in existence for determining the deflection of lithospheric plates under an applied transverse load. The most popular models treat lithospheric plates as thin elastic or thin viscoelastic plates. The equations governing the deflection of such plates have been solved successfully in two dimensions using integral transform techniques. Three dimensional models have been solved using Fourier Series expansions assuming a sinusoidal variation for the load and deflection. In the engineering context, the finite element technique has also been employed. The current aim, how

Typically, the problem of a plate on an elastic foundation has been approached by assuming that the foundation modulus (or modulus of subgrade reaction for a soil) remains constant as the plate deforms the foundation. If one were dealing with soil as the foundation material, it can be seen from a load-deformation plot for a particular soil, that this modulus would not be constant but would decrease as the deformations increase. The purpose of this thesis is to obtain an accurate solution that uses a more realistic model for the effect of the foundation behavior in the problem. When larger defl

Relatively large construction loads applied to immature slabs with their low elastic moduli will cause large initial elastic deflections. The high applied stress/developed strength ratio will cause significant creep, resulting in large long-term deflections. Shrinkage, while not related to construction loads, also contributes to long-term deflections. Studies reported by many investigators showed that the long-term deflections cannot be ignored in the design process and that the contribution of the effects of the construction loads cannot be ignored.

The concept of load analogy is used in the elastic and elastic-plastic analysis of isotropic circular and annular plates undergoing moderately large deflection. The effects of the nonlinear terms of lateral displacement and the plastic strains are considered as additional fictitious lateral loads, edge moments, and in-plane forces acting on the plate. The solution of an elastic or elastic-plastic Von Karman type plate is hence reduced to a set of two equivalent elastic plate problems with small displacements, namely, a plane problem in elasticity and a linear elastic plate bending problem.

Many of today?s steel bridges are being constructed with longer spans and higher skew.

In response to these problems, the NCDOT has funded this research project (Project Number 2004-14). Common dead load deflection prediction methods, which traditionally utilize single girder line (SGL) analysis, have been shown to over predict the dead load deflections; the inaccuracy can result in various costly construction delays and m

碩士<br>中華大學<br>機械工程學系<br>104<br>This study proposes an approximate solution based on energy method to solve the large deflection problem of rigidly-bossed micro plate of typical semiconducting material. The purpose is to simulate the physical condition of a bossed sensing or actuating device, The approach extends classical plate theory (CLT) method for solving a flat plate to a rigid bossed plate problem, first. Then energy-minimum potential energy principle is utilized that accounts for stretching and bending strain energy including Von Karman large deflection consideration to develop the appr

abstract: Stress-related failure such as cracking are an important photovoltaic (PV) reliability issue since it accounts for a high percentage of power losses in the midlife-failure and wear-out failure regimes. Cell cracking can only be correlated with module degradation when cracks are of detectable size and detrimental to the performance. Several techniques have been explored to access the deflection and stress status on solar cell, but they have disadvantages such as high surface sensitivity. This dissertation presents a new and non-destructive method for mapping the deflection on encapsu

碩士<br>元智大學<br>機械工程學系<br>96<br>In this investigation, the static deflection and harmonic vibration of laminated plate induced by piezoelectric actuators under mixed boundary condition are examined. Two piezoelectric actuators are surface bonded or embedded in the plate and are symmetric with the mid-plane. Electric voltages with the same amplitude and opposite sign are applied to the two symmetric piezoelectric actuators, results to the bending effect on the laminated plate. The bending moment is derived by using the theories of elasticity and piezoelectricity. This bending moment is then appl

碩士<br>中華大學<br>機械工程學系碩士班<br>99<br>The problem of large deflection of a pre-stressed un-symmetric layered plate with an elastic boss due to lateral pressure is studied. The governing equations were developed based on von-Karman plate theory for large deflection, which are further formulated in terms of lateral slope and radial force resultant via a non-dimensional and merging scheme. The small defection condition is considered, first, by neglecting the arising nonlinear terms, reducing to a simplified linear problem and thus a modified Bessel equation for the lateral slope. The linear analytical

The effects of material property and thickness on the stress distribution are examined through a parametric study. The flexural deflection of a simply supported plate subjected to the bending moment is derived basing on the plate theory. The deflection is validated with the 3-D finite element results.
