Rigid-tube computations of simple (transverse) shear in crystalline nanotube ropes (CNTRs) reveal that shear modulus and strength increase and decrease with the tube radius, respectively. High modulus to strength ratios suggest that dislocations play a minor role during their plasticity. The computed shear moduli are in agreement with previous studies, although shape change and rolling-based sh...

Flow kinematics estimations are necessary to determine how the deformation is partitioned in shear zones at different scales. Combining scales of structural analysis with quantitative vorticity constraint allows a more rigorous examination deformation. The Posada-Asinara zone (PASZ) northern Sardinia (Italy) crustal-scale km-thick transpressive zone, separating High- from Medium-Grade Metamorph...
