Transitional Failure of Carbon Nanotube Systems under a Combination of Tension and Torsion

Table 1

Loading cases considered for the simultaneous tension-torsion simulations. The tensile load (tension) and torsional moment (torque) are applied simultaneously in a proportional and quasistatic manner.
