water inrush were the drainage and pressure reduction, especially lowering the water table of the aquifer or causing different sizes of drawdown funnels actively and systematically. Table 6 Evaluation......
trend with those indicated in Figures 4 and 5. Particularly, a reduction of the lateral peak strain with increasing the stiffness of the filling rod can be observed. Figure 6 Typical curves of axial...]. Engineering Geology, 2003, 69: 219-231. DOI: 10.1016/S0013-7952(02)00283-1. [32] MONFARED M, DELAGE P, MOHAJERANI M. A laboratory investigation on thermal properties of the opalinus claystone [J]. Rock......
-solid thixoformed Al-Si-Cu-Mn-Fe alloys after thermal exposure at 300 °C were discussed. The results demonstrate that the elevated temperature tensile properties of semi-solid thixoformed alloys were significantly higher than those of gravity die cast and squeeze cast alloys, especially after thermal exposure for 100 h. The ultimate tensile strength (UTS) of semi-solid thixoformed alloys......

The damage and grain size distributions of the Ti-6Al-4V parts were accurately predicted by the FE simulation combining......
diagram (FLD) is usually assessed based on the reduction in thickness and localized necking during the specimens’ deformation. In their previous work over stretch forming of IN625 under different... in the HDR is due to the thermal softening, which made the material soft and helped to ease the material’s easy forming. The lubrication also provided an added advantage for the easy drawing of material......
of NiO oxides during the thermal cycling, which was also visually confirmed by SEM/EDS. Figures 8 and 9 show the surface and corresponding cross-sectional morphologies of both alloys after cyclic...) The released S diffuses into the alloy and attacks the alloy, leading to internal sulfidation. This sulfidation causes a reduction in S activity and an increase in O2- activity, resulting in basic fluxing......
. Fabrication of such components is a challenging task due to the vast difference in mechanical, thermal and electrical properties of the materials being used. Friction stir welding (FSW) is capable... of dissimilar materials is a challenging research task and a matter of concern for the engineers and scientists. The necessity to develop the machines/parts/systems that culminate in weight reduction, high......
) waves breakage This classification is in fact thermal treatment of rocks using any form of heat to induce weakening, spalling, melting and vaporizing of rocks. In principle, the mechanism of thermal... of a narrow heated channel in a sufficiently short time to create thermal shocks. Initially the power drawn from the source creates a conducting channel through the rock. Near the completion of this channel......
the various factors i.e., the mechanical properties, physical properties, thermal properties, magnetic properties, wear, oxidation, and corrosion behavior need to be considered while evaluating... approach of material selection using fuzzy logic. The proposed method was able to deal easily with the quantitative properties of the materials. There was a considerable reduction in the quantum......
