Abstract
Carbon nanotubes subject to large deformations reversibly switch into different morphological patterns. Each shape change corresponds to an abrupt release of energy and a singularity in the stress-train curve. These transformations, simulated using a realistic many-body potential , are explained by a continuum shell model. With properly chosen param eters, the model provides a remarkably accurate ''roadmap'' of nanotub e behavior beyond Hooke's law.
