Sentence examples for lasat from inspiring English sources

The Laser Shock Adhesion Test (LASAT) involving bi-dimensional shock wave propagation, namely the LASAT-2D, consists in measuring the interfacial crack diameter when implementing a set of laser shocks with increased laser power densities.

The final objective of this work is to enable a sound and relevant application of the LASAT on TBC systems for both modes.

In this study, a new method is proposed based on experimental results, which utilizes a TDLAS (Tunable Diode Laser Absorption Spectroscopy) instrument – GasFinder2.0® system and a dispersion model LASAT (Lagrangian Simulation of Aerosol Transport) as the measurement device and calculation model, respectively.

With this goal, the LASAT-2D CS was successfully applied directly on a TBC coated turbine blade.

From LASAT-2D curves, the role of the laser conditions like laser shock diameter and substrate thickness is discussed.

This discussion is illustrated through the results of the qualitative LASAT-2D method applied on two different TBC samples (as-coated and thermally-cycled).

From the resulting "LASAT-2D plots", adhesion strength could be obtained from tensile stress calculated at the interface with a finite element model of shockwave propagation combined to interface cracking criterion.

This work is focusing on the qualitative approach to compare adhesion on TBC systems directly through LASAT-2D plots.
