Thesis: A 2D Multiscale Procedure for Fatigue Crack Nucleation

Current Research:

ICF 12 Presentation: Stochastic Framework for Predicting Microstructurally Small Fatigue Life of AA 7075-T651

My work includes developing a filter approach to screen microstructural realizations, and combining the results with highly-detailed multiscale analyses in order to quantify the microstructurally small fatigue life of a given structural component.

Sponser: National Aeronautics and Space Administration (NASA)

Past Research:

Structural Integrity Prognosis System (SIPS)

Previous work includes developing Multiscale algorithms within a probabilistic finite element framework to apply boundary conditions on a realistic microstructure and to update continuum stiffness in order to represent damage on the continuum scale for use in analyzing fatigue of aerospace vehicles. This approach is currently being adapted to 3D.

Sponsored by: United States Defense Advanced Research Projects Agency (DARPA)

Basic Outline of Approach:

1. Analyze Continuum Structure

2. Extract Boundary Conditions for Polycrystal Model

3. Analyze Polycrystal Model

4. Update Continuum Stiffness

Background:

"It breaks your heart. It is designed to break your heart. The game begins in the spring, when everything else begins again, and it blossoms in the summer, filling the afternoons and evenings, and then as soon as the chill rains come, it stops and leaves you to face the fall alone. You count on it, rely on it to buffer the passage of time, to keep the memory of sunshine and high skies alive, and then just when the days are all twilight, when you need it most, it stops. Today, October 2, a Sunday of rain and broken branches and leaf-clogged drains and slick streets, it stopped, and summer was gone. . . . It breaks my heart because it was meant to, because it was meant to foster in me again the illusion that there was something abiding, some pattern and some impulse that could come together to make a reality that would resist the corrosion; and because, after it had fostered again that most hungered-for illusion, the game was meant to stop, and betray precisely what it promised."

--from The Green Fields of the Mind, by A. Bartlett Giamatti (Former MLB Commissioner and President of Yale University, and lifelong Red Sox fan)

I was born in the historic city of Newburyport, MA and grew up in the historic town of Danvers, MA (Formerly known as Salem Village, home of witchcraft hysteria). My undergraduate studies brought me the University of Vermont. Needless to say, it was far different from urban sprawl that encompasses most of eastern Massachusetts. I came to Cornell University to continue my work in the fall of 2003 and joined CFG in May of 2004.

As can be seen from the above quote I am an avid baseball fan. Congratulations to the World Champion 2004 and 2007 Boston Red Sox. I also enjoy hiking, camping and reading.
