Open seminars

Speaker : Professor Rodney S. Ruoff (Dept. Mech. Eng., Northwestern University, IL)
Subject : Mechanics of Nanostructures and Nanocomposites
Date : January 28, 2005 (Conference room 226, Faculty of Engineering bldg.8, Hongo campus)
Outline The topics to be discussed: (i) Experimental studies by my group 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.
