The presentation covers experimental and theoretical studies of nanostructures and nanocomposites. Following topic will be discussed.


(i) Experimental studies of carbon nanotubes and nanocoils, boron and metal boride nanowires, and carbon nanotubes projecting from the fracture surface of CNT composites (a) subjected to tensile loading (b) driven into mechanical resonance by mechanical or electrical excitation.


(ii) The ideal strength of materials & fracture in nanostructures (a) ab initio calculations of ideal strength (b) experimental work on nanostructure fracture (c) modeling of the fracture strength of nanostructures with 0, 1, 2 adjacent, 3 adjacent, …, n adjacent defects (d) following this summary of prior work, a new theory (developed with Nicola Pugno, Politecnico di Torino) for fracture of nanoscale structures will be presented: Quantized Fracture Mechanics.
