      Effect of yield penetration on column plastic hinge length 

      Megalooikonomou, K. G.; Tastani, S. P.; Pantazopoulou, Stavroula J. (2018)
      The required confined zone in critical regions of columns and piers undergoing lateral sway during earthquakes is related to the plastic hinge length where inelastic deformation and damage develops. The exact definition ...

      Evaluating the microstructure and performance of nanocomposite PVD TiAlBN coatings 

      Baker, M. A.; Klose, S.; Rebholz, Claus; Leyland, A.; Matthews, A. (2002)
      Physical vapour deposition (PVD) TiAlBN coatings can exhibit excellent wear resistance, with optimised coating compositions demonstrating a 150% increase in lifetime compared to standard TiAlN coatings in wet-cutting drill ...

      A mechanistic approach in defining inelastic rotation capacity of RC columns 

      Megalooikonomou, K. G.; Pantazopoulou, Stavroula J.; Tastani, S. P. (National Technical University of Athens, 2017)
      When a reinforced concrete (RC) column is subjected to lateral sway as a result of earthquake action, the large strain demand in the end sections is supported by development of strains in the anchorage. This causes the ...

      Spark ignitable Ni-Al ball-milled powders for bonding applications 

      Gunduz, I. E.; Kyriakou, A.; Vlachos, N.; Kyratsi, Theodora; Doumanidis, C. C.; Son, S.; Rebholz, Claus (2014)
      Ball milling of aluminum (Al) and nickel (Ni) particles at the NiAl composition can produce reactive powders with low spark ignition thresholds similar to magnetron sputtered multilayer foils (MFs). Such powders can replace ...

      Strong paramagnetism and possible ferromagnetism in pure carbon nanofoam produced by laser ablation 

      Rode, A. V.; Gamaly, E. G.; Christy, A. G.; Gerald, J. G. Fitz; Hyde, S. T.; Elliman, R. G.; Luther-Davies, B.; Veinger, A. I.; Androulakis, J.; Giapintzakis, John (2005)
      We report the production of a hierarchically nanostructured magnetic carbon foam by high-repetition-rate laser ablation of glassy carbon in Ar. The clusters contain both sp2 and sp3 bonded carbon atoms. The material contains ...
