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.

My name is Ling Zhu and I am currently a PhD student in Mechanical Engineering of University of Nebraska Lincoln. I got my bachelor degree in Civil Engineering from Nanjing University of Science and Technology, China and master degree in Engineering Mechanics from Zhejiang University, China. The research group I am now in is called Midwest Roadside Safety Facility ( mwrsf.unl.edu ) and I am doing the research of simulation of material failure. We are using nonlinear FE software LS-DYNA to simulate the design before performing real-life physical test to reduce the cost.

Point by point, here's the goods:

• I am currently enrolled at the University of Nebraska-Lincoln.
• Prior mechanics courses include: Mechanics of Materials, Advanced Mechanics of Materials, and I'm currently taking Mechanics of Composite Materials
• I received my Undergraduate degree in Civil Engineering from the University of Nebraska Lincoln.
• My strengths for this class...

My name is Jamilla Lutif. I am up to finish my Master in the Civil Engineering Department at UNL. My BS degree is also in Civil Engineering, and I got the BS degree at the Universidade federal do Ceara, in Brazil.

Dear all:

Please post your self-introduction online, following the instruction, but turn in the rest of your homework on paper to your teaching assistants.
