EXTREME shearography: High-speed shearography instrument for in-plane surface strain measurements during an impact event

This work presents the design and the latest experimental results on the surface strain measurements during an impact event obtained with the EXTREME high-speed shearography instrument. The shearography technique is used in this project to provide a quantitative measurement of the surface strain development at the first moments of the impact...

EXTREME shearography: Development of a high-speed shearography instrument for measurements of the surface strain components during an impact event

This work presents the design and preliminary results of a high-speed shearography instrument in development for surface strain components measurements during an impact event. Composite materials are vulnerable to extreme dynamic loadings such as blade off events or foreign object damage as their mechanical properties are strain rate...
