Relationship between inhomogeneous deformation and local texture in zirconium from multiscale image correlation

Padilla, Henry A.; Lambros, J.; Beaudoin, A.; Robertson, I.

The effect of local texture on inhomogeneous deformation is probed in strongly textured zirconium during compression. The use of in-situ digital image correlation at multiple length scales allows both qualitative and quantitative analysis of the relationship between grain orientation and patterns of deformation bands that form as the precursors to an adiabatic shear band. Experimental results indicate that basal textured zirconium does not deform homogenously at any of the length scales examined. ©2009 Society for Experimental Mechanics Inc.
