Vortex machining is a unique localized material removal process in which footprints of several nanometer in depth are obtained. It employs a resonating quartz tuning fork and a fiber attached on its upper tine. When submerged in a layer of slurry,...
In this work, a two-dimensional finite element model of orthogonal machining ofAISI 1045 steel is developed using the commercial non-linear finite element packageABAQUS. The material behavior is described using the Johnson-Cook constitutivelaw. Fu...
The use of biomaterials as drug delivery systems (DDS) eliminates the adverse side effects of systemic drug administration. Silica-based bioceramics have been widely studied as DDS and demonstrated a unique ability for controlled drug release loca...
ABSTRACTAJITH RAMESH: Modeling the creep behavior of torsional springs This dissertation presents a detailed model of the `overall' behavior of Torsional springs. Torsional springs (also called `Clock' springs) are a kind of spiral springs which a...
This dissertation presents applications of the finite element method in studying the durability of components used in aerospace (composites) and medical (hip implants) industries. In the first part of the dissertation the response of a fiber-reinf...
