Journal ArticleDOI
Experimental determination and empirical representation of out-of-plane displacements in a cracked elastic plate loaded in mode I
TL;DR: In this article, a Michelson interferometer is applied to a mode I fracture mechanic problem to investigate the out-of-plane displacement near the crack tip, and a mathematical formulation, using an exponential integral function, is then proposed to describe the surface displacement in the measurement area around the cracked tip.
Journal ArticleDOI
Grating Interrogations: from Small to Large Strain Measurement
TL;DR: In this article, the authors used a Fourier transform to characterize a cross grating marked on the surface of a specimen using a master grid and applied it to the analysis of the grating.
Mesures en mécanique par méthodes optiques
Fabrice Brémand,Mario Cottron,Pascal Doumalin,Jean-Christophe Dupré,Arnaud Germaneau,Valéry Valle +5 more
TL;DR: The photomecanique as discussed by the authors, which regroupe l'ensemble des metrologies optiques, offre une large palette of techniques de mesure without contact, souvent mises a profit for l'identification du comportement mecanique des materiaux dans les laboratoires comme pour le suivi des procedes de fabrication ou la tenue de structures dans l'industrie.
Journal ArticleDOI
In Plane Displacement Formulation for Finite Cracked Plates Under Mode I Using Grid Method and Finite Element Analysis
TL;DR: In this article, a grid method is used to experimentally determine the in-plane displacement fields around a crack tip in a single-edge-notch (SEN) tensile polyurethane specimen.
Journal ArticleDOI
Calculation of J-integrals using experimental and numerical data: Influences of ratio (a/W) and the 3D structure
TL;DR: In this paper, a grid method is used to experimentally determine the in-plane displacement fields around a crack tip in a Single-Edge-Notch (SEN) tensile polyurethane and PMMA specimens.
