The following content has been provided by the University of Erlangen-Nürnberg.

Elasticity of one-dimensional continua and nanostructures, which is a nice combination,

I guess, of topics that every engineering student should know from the very first semesters,

on the one hand, when it concerns beams and rods, with more advanced topics that are related

to nonlinear continuum mechanics plus atomistic modeling.

So our lecturer is Professor Ajit Kumar.

He's too modest to put his name here, but here you can see his name.

So Professor Kumar studied mechanical engineering, like most of you, I guess, initially at the IIT.

These are the most prestigious institutes in India, the Indian Institutes of Technology in Kharagpur,

till his bachelor degree.

He moved to the greatest country of all, not at that time, but now, nowadays,

to the Cornell University to pursue his Master of Science there, and then also later his PhD,

which was, I suppose, already a little bit in this direction here, multiscale modeling.

Yes, it was.

And after that he pursued his postdoc in the University of Minnesota,

so in total this was like a six-year stay in the greatest country.

And since 2012, until now, he is a professor at the renowned Institute of Technology of Delhi in India

in the mechanics department, applied mechanics department.

So, and we have, as the university here in Erlangen,

together with the Indian Institute of Technology in Delhi,

we have this four-year exchange program that is funded jointly by Indian and German institutions,

which has a lot to do with exchange, of course, and also education and lecturing.

And in this regard, we planned this little series here on topics that are in the center of the research

of Professor Kumar, on the one hand, and on the other hand, also fit nicely in various activities here in our environment,

not only here at the Chair of Mechanics, but also broadly in the technical faculty and beyond.

If you have read the flyer or the poster, you already got some of the motivation that whatever we do

can also be applied here in the area of DNA and various more biological questions,

but also, on the other hand, it has quite strong technical application,

if you think in terms of nanowires and things like that.

So, with that, I would say I hand over the stage to you, Ajit.

Thank you.

Enlighten us.

Sure.

Okay, so a very good morning, everyone.

So, before I start, could you please sign on this sheet?

I'm just passing it here.

So, as Professor Steinman said, I am Ajit Kumar and we are going to have this lecture on elasticity of one-dimensional continua and nanostructures.

So, we will, as you will see later on, we will study the one-dimensional structures both at continuum and at the nanoscale.

So, how the theory looks like at the continuum scale and at the nanoscale and how can the two theories be bridged together.

So, that is what I say here, a multi-scale viewpoint and I will have later on several slides,

which will tell you what are the various applications of this theory.

Okay, so let me just go to the next slide where I talk about where we come from.

So, you know, here we are.

So, we are three people here.

We, I also have two very good friends of mine, Prakhar Gupta and Smriti Singh.

They are working with me at IIT.

So, I think you will also hear from them.

And in fact, some of the things that we will learn here has been, you know, I worked together with Prakhar as part of his PhD.

So, you know, so he can tell a lot about, he can talk about it in a very nice way because that is his work.

Okay.
