Fracture of a 08KP Steel in Nano-Fragmented State

Yermishkin V.A., Tamayo M.P., Muñoz Aguirre N., Instituto Politecnico Nacional, MX

The evaluation of the resistance to the fracture toughness of metals and metal composites that work in the plastic regime require of the using of highly complex experimental methods and analysis which are not at [...]

Mechanical Damping due to Interface Motion in Micro-Resonators

Pawaskar D.N., Phillips R., California Institute of Technology, US

Mechanical damping strongly influences the sensitivity and resolution of nano-sensors and actuators. In this paper, we have investigated one of the key intrinsic mechanisms responsible for dissipation of vibrational energy in beams composed of a [...]

Size Effects and Scaling in Misfit Dislocation Formation in Self Assembled Quantum Dots

Friedman L.H., Weygand D.M., van der Giessen E., University of Groningen, NL

Growth islands due to large mismatch strain arising in Stranski-Krastanow (SK) and Volmer-Weber (VW) ﬁlm growth can be used to produce large arrays of quantum dots. This same mismatch strain may also cause misﬁt dislocations [...]
