Finite element analysis and experiments on hybrid laser assisted high-speed machining London South Bank University School of Engineering Depending on the specifications (type, pulse, energy and power), a Laser can either be used for efficient material removal, forming, bending, joining or for deposition.
The case element has been used to evaluate the thesis and here issues that arise when phd an innovative integrated modelling methodology between a computational fluid dynamics CFD software applied to compartment fires and a finite finite FE software applied to structural systems.
Stochastic Galerkin finite element methods (SGFEMs) are a popular choice for the numerical solution of PDE problems with uncertain or random inputs that depend on countably many random variables.The moving mesh finite element method (MMFEM) is a highly useful tool for the numerical solution of partial differential equations. In particular, for reaction-diffusion equations and multi-phase equations, the method provides the ability to track features of interest such as.When the global response of elastoplastic solids is analysed using the finite element method, the nonlinear load-displacement behaviour is linearised by dividing the total load into a number of discrete increments. Each of these load increments is applied in sequence until the total external load is in place.
PhD vacancy (4 years) on computational mechanics of large wind turbine blades University of Ghent Dept. of Materials Science and Engineering Over the last years, UGent-MMS has developed the stand-alone BladeMesher software for generating finite element models of large wind turbine blades.Read More
Thesis Supervisor: James A Sherwood, PhD, P.E. Professor, Department of Mechanical Engineering. iv ABSTRACT In 1974, the NCAA introduced metal bats into collegiate-level baseball as a cost-effective alternative to traditional wood bats. Manufacturers of bats can change very little in the case of wood bats other than the outside profile because the properties of the wood are at the mercy of.Read More
Abstract This thesis presents advances and applications of the eXtended Finite Element Method (XFEM). The novelty of the XFEM is the enrichment of the primary variables in the elements intersected by the discontinuity surface by appropriate functions.Read More
This thesis presents a framework for soft tissue modelling, facial surgery simulation, and facial movement synthesis based on the volumetric finite element method. Assessment of facial appearance pre- and post-surgery is of major concern for both patients and clinicians.Read More
In this thesis, several hybrid techniques which employ finite element and boundary element methods are presented. A finite element-boundary element method is presented for computing the scattering by cylindrical objects. The method uses artificial boundaries that can follow the contour of the scatterer so that the discretization region is minimized. More importantly, the method results in a.Read More
We propose a discontinuous Galerkin finite element method (DGFEM) for fully nonlinear elliptic Hamilton--Jacobi--Bellman (HJB) partial differential equations (PDE) of second order with Cordes coefficients. Our analysis shows that the method is both consistent and stable, with arbitrarily high-order.Read More
Next: 2.1 The Systems of Up: Dissertation Hajdin Ceric Previous: 1.5 Motivation and Outline. 2. Finite Element Method A good number of practical TCAD problems can be formulated in terms of partial differential equations (PDE) subject to specified boundary conditions. Except in the case of simple and geometrically well-defined problems, closed form analytical solutions are impossible. For.Read More

This present thesis proposes a novel approach for coupling finite element and boundary element formulations using a Loop subdivision surface discretisation to allow efficient acoustic scattering analysis over shell structures. The analysis of underwater structures has always been a challenge for engineers because it couples shell structural dynamics and acoustic scattering.Read More
The finite element method has been used to develop a methodology to model the actual machining process that produced the aircraft component. The finite element model that has been developed so far was able to demonstrate the effects of redistribution of the residual stresses on the distortion of the final machined component. It was found that.Read More
