Laser line scanning thermography for surface breaking crack detection : modeling and experimental study
Nithin Puthiyaveettil,K. Renil Thomas,Sreedhar Unnikrishnakurup,Philipp Myrach,Mathias Ziegler,Krishnan Balasubramaniam +5 more
TL;DR: In this paper, the potentiality of laser line thermography in crack detection at room temperature was investigated, and a 3D model for laser thermography was developed for the heat distribution during laser heating and validated with experimental results.
Journal ArticleDOI
Ultrasonic torsional guided wave sensor for flow front monitoring inside molds.
TL;DR: An ultrasonic torsional guided wave sensor has been discussed for monitoring the movement of flow front during filling of resins in opaque molds.
Journal ArticleDOI
Assessment of sensitization in AISI 304 stainless steel by nonlinear ultrasonic method
Saju T. Abraham,Shaju K. Albert,C. R. Das,N. Parvathavarthini,B. Venkatraman,R. S. Mini,Krishnan Balasubramaniam +6 more
TL;DR: In this paper, a nonlinear ultrasonic technique has been developed to evaluate sensitization in Type 304 stainless steel and the results showed a good correlation between the degree of sensitization measured by the electrochemical potentiokinetic reactivation test and the ultrasonic nonlinearity parameter.
Journal ArticleDOI
The disappearing solar filament of 2003 june 11: a three-body problem
TL;DR: In this paper, the authors show that the magnetic disturbance propagates from a mature active region to a quiescent filament by direct magnetic connection, but does so indirectly via magnetic coupling with the established region.

In-situ, real time viscosity measurement of molten materials with laser induced ultrasonics
Jagdish P. Singh,Krishnan Balasubramaniam,R. Daniel Costley,Vimal V. Shah,Christopher B. Winstead +4 more
TL;DR: In this article, a method of remotely measuring the viscosity of molten materials such as melt glass, melt alloys, etc. during processing of the material is proposed. But this method is not suitable for the processing of complex materials.
