High energy 2D X-ray powder diffraction experiments are widely used for lattice strain measurement. The 2D to 1D conversion of diffraction patterns is a necessary step used to prepare the data for full pattern refinement, but is inefficient when only peak centre position information is required for lattice strain evaluation. The multi-step conversion process is likely to lead to increased error...

the effect of welding residual stresses that was created in thin infill plate of steel plate shear wall system during constructional processes was studied in this research. residual stresses in a welded structure is the result of the non-uniform expansion and contraction and plastic deformation of the weld and surrounding base metal due to heating and cooling cycle, during welding process, this...

Piezoelectric properties of three sol-gel derived Pb Zr0.53Ti0.47 O3 thin film specimens of different thicknesses integrated onto Pt/Ti/SiO2 Si substrates are investigated to delineate the influence of residual stress on the strain-field response characteristics from other thickness related effects. Residual tensile stresses are determined from wafer curvature measurements for films ranging in ...

The Maximum Residual Energy Path (MREP) routing has been shown an effective routing scheme for energy conservation in a battery wireless network. Past studies on MREP are based on the assumption that the transmitting node consumes power, but the receiving node does not. This assumption is false if acknowledgement is required, or if the ad hoc network has deployed the energy-conservation mode (s...

Stepped spillways are designed to increase the rate of energy dissipation on the chute and to reduce the size of the downstream energy dissipator. It is essential to predict accurately the turbulent dissipation above the steps for large discharges per unit width corresponding to the skimming flow regime. New measurements were conducted in a large facility with a channel slope of 21.8o and a ste...

A theoretical study of diamond/silicon (001) interface structures with and without graphitic interlayers using a density functional based tight–binding molecular dynamics method is presented. The study is motivated by recent progress towards diamond heteroepitaxy on Si (001) using the bias technique. The proposal by Robertson (1995) that an initial graphitic deposit with the graphite planes nor...

Neutron diffraction was used to measure the residual stress distribution in an FeAl weld overlay on steel. It was found that the residual stresses accumulated during welding were essentially removed by the post-weld heat treatment that was applied to the specimen; most residual stresses in the specimen developed during cooling following the post-weld heat treatment. The experimental data were c...

Brittleness is an essential parameter to determine the deformation and failure behavior of rocks, it useful quantify brittleness rocks in numerus engineering practices. A novel energy-based evaluation index proposed this study, which redefines dissipated proportion ultimate elastic strain energy relative post-peak residual energy. series conventional triaxial compression (CTC) tests were perfor...

Abstract Residual stress relaxation induced by the application of mechanical loads is determined nature residual stress, elasto‐plastic material properties, and type applied load. Despite importance first load cycle, analytical models available in literature generally assumed as a continuous process. machining on Inconel 718Plus superalloy cylindrical specimens was measured before after cycles ...
