x-100 steel is one of the most recently developed materials for production of gas transportation pipelines. this material is severely anisotropic. smooth and notched round bars with different notch radius and flat notched specimens with different notch radius and notch depth in tension are tested to characterize the failure of this material under quasi-static loading condition. triaxiality fact...

Compared with other natural fibers, coir fiber has good strength characteristics and long-term anti-biodegradation ability. At present, most studies on randomly distributed fiber-reinforced soil have focused cohesionless or granular soil. In this paper, the influence of deviatoric stress shear index red clay different content was assessed by a consolidated undrained (CU) triaxial compression te...

During the welding, many phenomena occur. The materials deform under action of residual stresses. This tendency is due to high gradients temperature during process. These deformations are really difficult for professionals operating in area. In goal predict these variations, one has established behaviour laws which will be applied evaluate stresses and strains. research focused on study Thermal...

Abstract In this study, the stress–strain curves of sandstone soaked in 5% NaCl and K 2 SO 4 solutions under different loading unloading paths were obtained by carrying out confining pressure tests on specimens. Thereafter, strength, deformation, failure characteristics specimens analysed. First, capacity was found to be greater than those , amount increased order increasing axial &lt; constant...

Fractured-rock aquifers display spatially and temporally variable hydraulic conductivity generally attributed to variable fracture intensity and connectivity. Empirical evidence suggests fracture aperture and hydraulic conductivity are sensitive to in situ stress. This study investigates the sensitivity of fractured-rock hydraulic conductivity, groundwater flow paths, and advectiondominated tra...

We have conducted highP-Tsynchrotron X-ray and time-of-flight neutron diffraction experiments as well as indentation measurements to study equation of state, constitutive properties, and hardness of nanocrystalline and bulk nickel. Our lattice volume-pressure data present a clear evidence of elastic softening in nanocrystalline Ni as compared with the bulk nickel. We show that the enhanced over...

In the search for high-energy density materials for Li-ion batteries, silicon has emerged as a promising candidate for anodes due to its ability to absorb a large number of Li atoms. Lithiation of Si leads to large deformation and concurrent changes in its mechanical properties, from a brittle material in its pure form to a material that can sustain large inelastic deformation in the lithiated ...
