Monitoring the deformation of carbon nanocoils under axial loading
Toyohashi, Japan (SPX) Feb 19, 2015
Carbon nanocoils (CNCs) composed of helical shaped carbon nanofibers have potential applications including mechanical springs and nano-solenoids. There are some reports which measure the spring constant of CNCs. However, the CNC response to prolonged stretching, which includes initial elastic elongation to large-scale deformation in the plastic regime and subsequent tensile fracture followed by post-fracture contraction and the release of the applied strain, remains undetermined. It is crucially i ... read more
