Sentence examples for under unload from inspiring English sources

Consequently, simulation results show that this AGPSO optimized approach outperforms than compared methods with higher efficiency and better quality no matter whether the HTRS system works under unload or load conditions.

For the tunnel problem, the tangential stress is under loading, while the radial stress is under unloading condition.

The closed-form explicit expression for the complete stress strain relation of rock materials containing cracks under unloading is obtained.

Tensile failure and orderly failure surfaces occur under unloading conditions while irregular damaged rock blocks are produced during loading failure.

The mechanical behaviors of crack-weakened rock masses under unloading are different from those of crack-weakened rock masses under loading.

The formation of an excavation damaged zone is dependent on three main aspects: time-dependent macroscopic stress field during excavation, constitutive model under unloading condition, and initial microcracks.

The experimental results indicate that the deformation of the coal-rock body is stronger under unloading conditions than in the CTC tests.

There is little systematic study of the evolution of permeability under unloading conditions during the mining of coal and rock and only a few studies have examined the relationship between microscopic damage and permeability during loading (Xie et al. 2013).

With the decrease of temperature, the yield strength and failure strain increase, but the yield strength and failure strain under unloading are obviously less than that under loading, and their difference also increases with a decreasing temperature.

It is found that the yield strength under unloading is obviously less than that under loading and the difference of the yield strength between the two stress paths increases with an increasing pressure, but the failure strains under the two stress paths do not differ greatly.

The results show that the complete stress strain relation and the strength of rock materials under unloading depend on the crack spacing, the fracture toughness of rock materials, orientation of the cracks, the crack half-length and the crack density parameter.
