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.
Using concepts of hierarchical multi-scale modeling, we report development of a mesoscopic model for single wall carbon nanotubes with parameters completely derived from full atomistic simulations. The parameters in the mesoscopic model are fit to reproduce elastic, fracture and adhesion properties of carbon nanotubes, in this article demonstrated for (5,5) carbon nanotubes. The mesoscale model enables one to model the dynamics of systems with hundreds of ultra-long carbon nanotubes over time scales approaching microseconds.
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.
1. Introductory
Recently, there has been some active discussion on topics like:
-- Open-source textbooks
-- Comparing lecture notes
-- Unification of mechanics
-- Wikipedia and Citizendium
Most visitors/users of iMehanica will be aware of Wikipedia. Well, there is a new project of this kind underway. To quote from its "mission statement":
The Citizendium (sit-ih-ZEN-dee-um), a "citizens' compendium of everything," is an experimental new wiki project. The project, started by a founder of Wikipedia, aims to improve on that model by adding “gentle expert oversight” and requiring contributors to use their real names.
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.
