Lec 21: Adventures in Nonlinear Structural Mechanics

The video was recorded as a part of the "Mechanics Lecture Series" of "The Mechanics Discussions" forum. This recording is of Lecture 21 on "Adventures in Nonlinear Structural Mechanics" and presented by Dr. Ramsharan Rangarajan (Indian Institute of Science, Bangalore). Website of Dr.Ramsharan Rangarajan: https://mecheng.iisc.ac.in/~rram Abstract of the lecture For many engineers, structural mechanics stops at Euler buckling. For others, it starts after. Indeed, an emerging paradigm in mechanics considers geometric nonlinearity and buckling phenomena as features to be exploited rather than as modes of failure. The principles underlying this emerging field enjoy two distinctive features- dependence on aspect ratios rather than absolute length scales and near independence from the material constitution. Hence, these principles promise to be useful, say, in examining the mechanics of graphene nanostructures, designing flexible electronic devices, or even deploying structures in space. At the talk, I will discuss two examples from my group’s work on studying the mechanics of slender elastic structures. The first concerns how flexible structures can function like robots. The second example concerns various aspects of modeling and experimenting elastic ribbons. I hope that these examples will highlight the multi-faceted nature of challenges in the field as well as opportunities for designing novel engineering applications.
