Adhesive tape loops
Krishnan Suryanarayanan, Andrew B. Croll, Harmeet Singh
We present an experimental and theoretical study of the mechanics of an \emph{adhesive tape loop}, formed by bending a straight rectangular strip with adhesive properties, and pres…
Self-contact in a buckled elastica
Krishnan Suryanarayanan, Parth Patel, Anup Kumar Pathak +1
We explore the mechanics of a terminally loaded buckled elastica under frictionless self-contact. With the aid of two integrals associated with the elastica, we propose a scale-inv…
A theory of locally impenetrable elastic tubes
Krishnan Suryanarayanan, Harmeet Singh
We present a reduced-order theory for locally impenetrable elastic tubes with uniform circular cross-section. The constraint of local impenetrability is incorporated into a variati…
Work and Activation in a Nematic Polymer Network Ribbon
H. Singh, K. Suryanarayanan, E. G. Virga
We study spontaneous deformations of a ribbon made of nematic polymer networks and activated under the action of a mechanical load. We show that when such ribbons are activated app…
