Experimental and theoretical/numerial investigations of thin films bonding strength

by A.G. Youtsos, M. Kiriakopoulos and Th. Timke,
European Commission, Joint Research Centre, Institute for Advanced Materials
Theoretical and Applied Fracture Mechanics, Volume 31, Issue 1, February-March 1999, Pages 47-59

Beginning of Paper Abstract:
" A laser spallation facility has been developed to measure the strength of planar interfaces between a substrate and a thin coating. This quantity is a central requirement in contemporary thin film and protective coatings technology and its successful measurement should improve the scientific/technological potential for the design of advanced composites, protective coatings of composites that operate in hostile environments, and in joining of dissimilar materials...

Subnanosecond velocimetry with a new kind of VISAR

by Ken E. Froeschner; J. S. Froeschner; A. G. Youtsos; T. Timke; M. Kiriakopoulos
SPIE proceedings vol 2869
22nd International Congress on High-Speed Photography and Photonics,
Dennis L. Paisley; Alan M. Frank, Editors, pp.1058-1064
Date: 28 May 1997

Beginning of Paper Abstract:
"A fresh approach to the principles of the delay leg interferometer which was ultimately developed by Barker, Hemsing and others as the `VISAR' (Velocity Interferometer System for Any Reflector) has resulted in an implementation which is simple, reliable, cost effective and capable of velocity measurements with sub-nanosecond time resolution. Results from laser induced shock exfoliation experiments which measure the adhesion strength of thin films on ceramic substrates are reported..."
