Helical amorphous nanosprings have attracted particular interest due to their special
mechanical properties. In this work we present a simple model, within the framework of the
Kirchhoff rod model, for investigating the structural properties of nanosprings having
asymmetric cross section. We have derived expressions that can be used to obtain the
Young's modulus and Poisson's ratio of the nanospring material composite. We also
address the importance of the presence of a catalyst in the growth process of amorphous …
