fracture mechanics

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.

Hi all,My name is Emmeline Lemos, I am a current Master student in Civil Engineering at University of Nebraska-Lincoln. I took my bachelor degree in Civil Engineering at my home country-Brazil. When I decided to leave my country and to come to graduate school,  I came with the great desire to learn more, and to try to absorb as much as possible from teachers, classmates and this new world that I'm surround by. Definitely, this desire to learn is one of my strengths and makes me overcome the challenges.  

As can be seen from my previous and current degree, most of my background is in Civil Engineering which give me not so much knowledge in Mechanics and been one of my weakness. But, Fracture Mechanics is not the first class that I’m taking in this field; I already took FEM and Continuum Mechanics.

My name is Jeff Chambers, I am a 1^st year PhD candidate in the Department Aeronautics and Astronautics at MIT. I received my BS in Mechanical Engineering from the University of California, Santa Barbara. While at UCSB, I worked with Prof. Keith Kedward investigating impact of composites. I did my MS in Aero/Astro at MIT working with Prof. Brian Wardle on durability of structural health monitoring systems. My PhD project is investigating failure theories for traditional composites. I will be working with Prof. Paul Lagace. My research lab is the Technology Laboratory for Advanced Materials and Structures (TELAMS).

Lecture 7.  Stability of large scale yielding crack growth & fracture mechanisms

I am Nitin Sharma, enrolled as M.S. student in Mechanical Engg. at UNL. I did my B.Tech in Mechanical Engg. in India. Worked as an Application Engineer in CAE, for some years, before deciding to take sabbatical and head back to school. Other courses that I have taken in solid mechanics include Mechanics of Materials and Mechanics of Composite Materials (currently enrolled). I feel that my experience with Finite Element codes would help me simulate crack propogation numerically. However, coming back to school after a long time makes me little out of touch with some mathematical concepts.
