Web1 de mar. de 2009 · Selected experimental measurements and theoretical predictions for the magnitude of long-range internal stress in monotonically and cyclically deformed metals are assessed and recently developed, spatially-resolved X-ray micro-beam techniques for direct measurements of long-range internal stress are discussed. The results of … Web31 de out. de 2001 · (2) Gradients of local strain and local flow stress are unambiguously related to deformation-induced long-range internal stresses. (3) Arrays of geometrically necessary dislocations act as sources of the internal stresses which cause a redistribution of the stress on a local scale, permitting the compatible deformation of neighbouring …

Phan et al., Synchrotron X-Ray microbeam diffraction measurements of full elastic long range internal strain and stress tensors in commercial-purity aluminum processed by multiple passes of equal-channel angular pressing. Acta Mater. 112, 231–241 (2016) CrossRef Google Scholar WebLong-range internal stresses (LRIS) are investigated in a [112]-oriented tensile-copper single crystal. The three-dimensional investigation of asymmetric X-ray profiles, measured by a high resolution diffractometer and using all Bragg reflections, allows the determination of the full long-range strain tensor. The corresponding stress tensor, determined by the … i bounce to the beat of my drum

Few studies have evaluated LRIS using convergent beam electron diffraction (CBED) in cyclically deformed single crystals oriented in single slip … Web1 de dez. de 2006 · It is shown by a simple model that the long-range internal stresses are a necessary consequence of the plastic strain mismatch between the soft cell interiors and the hard cell walls. Finally, it is shown that, with appropriate consideration of the long-range internal stresses, the macroscopic flow stress must be defined as a weighted average … ibound gms
