In this study, based on data from instrumentation Kaboodval earth dam, pore pressure, stresses and the meeting of the dam construction period compared with the values of numerical analysis. For this purpose, during the construction of the dam using Mohr-Coulomb model behavior, the softening, hardening model has been analyzed and pore pressure, stresses in the body and its meeting with instrum...
Using a concurrent multiscale approach we demonstrate that the local environment of transition-metal solutes in refractory bcc metals has a large effect on the mobility and slip paths of dislocation. The results reveal that solid solutes or nanoclusters of different geometries may lead to solid-solution hardening or softening, in agreement with experiment, including spontaneous dislocation glid...
We demonstrate that the changes in the elastic properties of the FeAs systems, as seen in our resonant ultrasound spectroscopy data, can be naturally understood in terms of fluctuations of emerging nematic degrees of freedom. Both the softening of the lattice in the normal, tetragonal phase as well as its hardening in the superconducting phase are consistently described by our model. Our result...
Magnetic hardening and generation of room-temperature ferromagnetism at the interface between originally nonmagnetic transition metals and π-conjugated organics is understood to be promoted by interplay between interfacial charge transfer and relaxation-induced distortion of the metal lattice. The relative importance of the two contributions for magnetic hardening of the metal remains unquantif...
The aim of this study was to clarify how the microstructural changes during and after phase transformation determine the age-hardenability of an Au-Ag-Cu-based dental alloy. The rapid increase in hardness in the initial stage was the result of rapid atomic diffusion by spinodal decomposition into metastable Ag-rich’ and Cu-rich’ phases. The constant hardening after apparent initial hardening wa...
