Although grinding is considered one of the more established manufacturing processes, it is still relatively poorly understood. In particular, the interaction of the wheel with the workpiece at times seems more like an art than a science. In this presentation, a 3-D topographic measurement approach which encompasses both the wheel and the workpiece will be presented. The topographic information obtained from the wheel will be applied to a model to predict the workpiece surface generated which will then be verified by experimentation. The prelimi ....etc

Ultrasonic methods enjoy the great capabilities in solving various problems associated with structural engineering and engineering materials. In this seminars, a host of research works and studies in this field carried out by the speaker will be presented to demonstrate the broad spectrum of their applications in aerospace engineering. Focus will be on nondestructive evaluation (NDE) and characterization of aerospace materials such as composites. Topics to be presented in the seminar include (1) 3-D imaging of damage in composites, (2) echo det ....etc

Over the last decade, particle tracking microrheology has matured as a new tool for complex fluids research. The main advantages of microrheology over traditional macroscopic rheometry are: the required sample size is extremely small (~ 1 mL); local viscoelastic properties in a sample can be probed with high spatial resolution (~1-10 mm); and the sample is not disturbed by moving rheometer parts. I will present two examples of recent work in my group that highlight how these characteristics can be exploited to acquire unique information about t ....etc

Abstract

To analyze a new endodontic sealer material commercially known as Resilon and to describe in detail the experimental techniques employed that lead to the identification of the composite material.
Methods

An extensive structural, thermal, and physical characterization was used to identify a new endodontic sealer material using the following techniques: Fourier transform infrared (FTIR) spectroscopy, nuclear magnetic resonance (NMR) analysis, X-ray fluorescence spectrometry (XRF) technique, X-ray diffraction (XRD) measurement, th ....etc

Objectives:
Rural areas in developing countries have energy crisis due to oil price increase on one hand and the depletion of traditional fuel resources such as firewood. In developing countries, the major part of energy requirement is for the domestic use for cooking, water, lighting and drinking water supply. Methane from biomass which is abundant in rural areas can be utilized to generate heat and electric energy. To make this possible ....etc

Atomistic Characterization of Dislocation Nucleation and Fracture



One of the central objectives of multiscale materials modeling is to develop and apply simulation techniques to uncover atomic-level mechanisms without the significant limitations on system size and simulation time inherent to purely atomistic methods. In this context, I have made two contributions. I developed an interatomic potential finite element method (IPFEM) to study homogeneous dislocation nucleation by nano-indentation. The implementation of IPFEM facilitates sim ....etc
