ES 242r

Problem Set 2

I am working on my PhD in Biomedical Engineering at the University of Neb. and have enrolled inES 242r because failure modes of many orthopedic implants can be attributed to initial flaws & fractures of material coatings.  This course, albeit, focuses on ductile materials, the principles seem relevant.

Dear Students of ES 242r / ENGM 940:

You may be interested in reading about the self-introductions of your fellow students. 

The attached notes are written mainly for myself. Most figures are missing. I'll draw these figures in class. So please take good notes in class.

I am pretty new to having a class that is fully powerpoint presentations and am wondering how everyone else is coping with it. Does anyone have any pointers or useful ways they keep notes in powerpoint classes? Printing the notes before hand? Anotating directly on the notes? Having a seperate notebook for notes and seperate handouts of presentation, etc etc?

I am a PhD student at the University of Nebraska Lincoln. I obtained MS in Engineering Mechanics from the University of Nebraska Lincoln, where my thesis was focused on numerical simulation of elastic wave propagation in polycrystalline material, and Bachelor of Engineering in Mechanical from Pune University, India. At present I am working with Dr. Joseph A. Turner in the Ultrasonics and Vibration group. My research is primarily focused on the ultrasonic wave propagation in heterogeneous media using statistical approaches. My research has both theoretical/numerical and experimental aspects for materials characterization and nondestructive testing purposes.

Hi my name is Karla Polivka. I am working part-time on my PhD degree in Mechanical Engineering at the University of Nebraska-Lincoln (UNL). What I mean by part-time is that I have been taking one class a semester for the last 5 semesters. I also received my Bachelors and Masters degrees in Mechanical Engineering from UNL.

I'm Xuanhe Zhao, a first year PhD student working in Suo's Group, at Harvard University. Prior to coming to Harvard, I obtained a Master Degree in Materials Engineering from University of British Columbia.

The courses I have taken in solid mechanics include Elasticity taught by Zhigang, Plasticity taught by Prof. J. Vlassak, and Solid Structure and Defect taught by Prof. F. Spaepen. Currently, I'm also in the class of Advanced Elasticity given by Zhigang.

My name is J. Alberto Ortega, and I am a PhD student in civil engineering at the Massachusetts Institute of Technology (MIT). My undergraduate education took place in Texas A&M University (I am a proud member of the Fightin’ Texas Aggie Class of 2002, WHOOP!), majoring in Structural Engineering. I recently obtained my Master of Science degree in Structures and Materials from MIT.

    I am Ashwani Kumar Goel, currently pursuing my Ph.D. from Engineering Mechanics Department, University of Nebraska Lincoln. I am from India. I have taken my Bachelors degree in Mechanical Engineering from HBTI, Kanpur,India and my Masters degree in Applied Mechanics from IIT, Delhi, India. I have taken lots of courses related to solid mechanics starting from my undergraduation. I have taken strength of materials ,applied mechanics, mechanics of solids during my undergraduate degree and applied elasticity, theory of plasticity, theory of plates and shells, continuum mechanics, linear viscoelasticity during my graduate degree. The group I work in focuses on theoretical, computational and experimental methods for the modeling and analysis of materials and the simulation of their response. I have been part of this group for about two and half years and focusing on theoretical and computational methods to extract material characteristics from novel experimental methods and in the implementation of these characteristics into simulations.

My name is Adrian Podpirka and I am a first year graduate student at Harvard studying Applied Physics. My undergraduate major was material science and engineering at Columbia University. Before taking fracture mechanics this semester I have taken Solid Mechanis (ES 240) with professor Suo.
