Residual Stress Measurement by Electronic Speckle Pattern Interferometry [PDF]
, 2007 The existence of residual stresses affects both safety and lifetime. Thus the determination of these stresses is very important. The ESPI (Electronic Speckle Pattern Interferometry) and Hole- Drilling combined method seems to be an appropriate technique ...

Topological transformations of speckles
, 2019 Deterministic control of coherent random light is highly important for information transmission through complex media. However, only a few simple speckle transformations can be achieved through diffusers without prior characterization. As recently shown,

PISCO2: the new speckle camera of the Nice 76-cm refractor
, 2014 We present the new speckle camera PISCO2 made in 2010-2012, for the 76-cm refractor of C\^ote d'Azur Observatory. It is a focal instrument dedicated to the observation of visual binary stars using high angular resolution speckle interferometry techniques

Damage accumulation near the cold-expanded hole due to high-cycle fatigue by crack compliance method
Fracture and Structural Integrity, 2021 The novel destructive method is implemented for quantitative assessment of fatigue damage accumulation in the stress concentration zone accompanied by residual stress due to cold expansion of the through-thickness hole. Damage accumulation is reached by

Information retrieval from holographic interferograms: Fundamentals and problems [PDF]
Holographic interferograms can contain large amounts of information about flow and temperature fields. Their information content can be very high because they can be viewed from many different directions. This multidirectionality, and fringe localization

Characterization on crack propagation of nuclear graphite under three-point bending
Nuclear Materials and Energy, 2019 The fracture properties of graphite produced in China, named as CLG, were studied by performing three-point bending tests on center-notched beams. The load-deflection (P-δ) curves and load-crack mouth opening displacement (P-CMOD) curves of the beams in ...
