Title of Document: AN ANALYTICAL APPROACH FOR FATIGUE LIFE ESTIMATION OF COPPER TRACES FOR DESIGN OPTIMIZATION IN ELECTRONIC ASSEMBLIES. Sandeep Menon, Doctor of Philosophy, 2015 Directed By: Professor Michael G. Pecht, Department of Mechanical Engineering This dissertation investigates the durability of the copper traces using experimental results from a fully reversed four point bend test and...
Titanium alloy sheet metal shows promising applicability in the aerospace industry with excellent mechanical properties, while its limited room-temperature formability is essential to be improved by thermal-assisted methods, expensive equipment and much energy consumption. In this work, flexible free incremental forming process adopted manufacture Ti6Al4V free-form surface panel at room tempera...
Details of a unified creep-plasticity theory, based on the concept of an internal time, are presented, and a geometric interpretation of such a theory is given. A' tangent-stiffness' formulation, for the finite-element/boundary-element calculation of weak solutions of the strain-history in the structure, is presented. An implicit algorithm of generalized mid-point radial mapping for computing t...
A numerical framework for the simulation of sheet steel stamping forming is presented. The main problems, the equations of motion, the constitutive relation, the initial conditions, boundary conditions and contact conditions, are presented in detail. Based on this, the finite element model is established and solved for exploring the changes in laws of stress, strain and so on. The information o...
We present a Finite Element (FE) approach to model the conductivity and strain-sensing capabilities of Carbon Nanotube (CNT) reinforced polymer composites. A periodic Representative Volume Element (RVE) is constructed based on measurable statistical descriptors of the microstructure, and its response is simulated by concurrent electrical and mechanical FE analyses; the scatter of the prediction...
In this work we report on a high-throughput mass spectrometry-based technique for the rapid high-resolution identification of Campylobacter jejuni strain types. This method readily distinguishes C. jejuni from C. coli, has a resolving power comparable to that of multilocus sequence typing (MLST), is applicable to mixtures, and is highly automated. The strain typing approach is based on high-per...
