We present a method that deforms an image plane to visually meet the shape and pose of a manifold surface. The user provides constraints that couple a small number of surface points with their corresponding image pixels to initially deform the plane. Matching, based on geodesic distances, couples additional points, followed by a second deformation that brings the image plane into its final pose...

Fe-Mn-C austenitic steels exhibit outstanding high-ductile deformation in their plastic regions along with significant microstructural evolution. In this study, to characterize the microstructural evolution during deformation of these steels, line-profile and texture analyses were carried out using X-ray diffraction. The convolutional multiple whole profile fitting procedure was used for a line...

Magnesium silicates are the dominant minerals in the earth’s mantle. Their preferred orientation is important for understanding the rheology and seismic anisotropy in the deep earth. Here we report results of radial synchrotron diffraction diamond anvil cell (DAC) experiments on San Carlos olivine, axially compressed to 50 GPa. Experiments were performed at room temperature, except for brief la...

[1] Deformation and texture formation in (Mg, Fe)SiO3 post perovskite (ppv) is a potential explanation for the strong seismic anisotropy that is found in the D00 layer of the Earth. However, different experimental approaches have resulted in different lattice preferred orientations (LPO) in deformed ppv that have led to ambiguity in the interpretation of deformation in the lowermost mantle. Her...

The deformation response and texture evolution of aluminum alloyed Hadfield steel polycrystals is explored in the presence of high-density islocation walls. A recently developed visco-plastic self-consistent model accounting for the contribution of the dense dislocation walls to strain ardening was utilized in predicting the room temperature deformation response under tension and the accompanyi...

Deformation behaviour of rolled AZ31 sheets that were subjected to the accumulative roll bonding was investigated. Substantially refined microstructure of samples was achieved after the first and second pass through the rolling mill. Sheets texture was investigated using an X-ray diffractometer. Samples for tensile tests were cut either parallel or perpendicular to the rolling direction. Tensil...

The plastic deformation behavior of twinning-induced plasticity steels of composition Fe–25Mn–3Si–3Al are investigated by means of in situ synchrotron high-energy X-ray diffraction and compared to self-consistent simulations. It is the first time the alternating interaction of {1 1 1} <1 1 0> slip and {1 1 1} <1 1 2> twinning have been directly observed in situ while undergoing uniaxial tension...

This paper presents a novel dynamic terrain multiresolution rendering method by utilizing the capabilities of current generation GPUs. Firstly, the terrain depth offset map texture that represents the appropriate offset values is generated through rendering to texture, which is used to deform terrain in vertex shader. Then in order to accurately represent the fine terrain detail created by defo...

The evolution of texture as a function of recrystallization has been characterized for hot-rolled AA1050. Samples prepared from a hot rolled sheet were annealed isothermally for sufficient time to allow complete recrystallization. The spatial orientation variation within the deformed microstructure of nucleation, growth and orientations of recrystallized grains is examined. The microstructural ...
