(2018) 25: 2107-2118 DOI: https://doi.org/10.1007/s11771-018-3900-y Numerical and experimental investigation of rock breaking method under free surface by TBM disc cutter ZHANG... Nature 2018 Abstract: To study the rock breaking method under the free surface induced by disc cutter, the rock breaking simulations were first conducted based on the discrete element method......
J. Cent. South Univ. (2015) 22: 413-420 DOI: 10.1007/s11771-016-3086-0 Free vibration analysis of non-homogeneous orthotropic plates resting on Pasternak elastic foundation by Rayleigh-Ritz method... Berlin Heidelberg 2015 Abstract: Free vibration analysis of non-homogeneous orthotropic plates resting on a Pasternak type of elastic foundation is investigated. A set of admissible orthogonal polynomials......
, the element free Galerkin method (EFGM) has favorable advantages such as stable solving process, high accuracy degree of result, convenient post-processing, eliminating volume lockup and simpler forms[10...J. Cent. South Univ. Technol. (2007)06-0858-06 DOI: 10.1007/s11771-007-0163-4 Buckling analysis of super-long rock-socketed filling piles in soft soil area by element free Galerkin......
Effect of surface free energy of ceramic glaze on oil droplet shape and its behavior in water LIANG Jin-sheng(梁金生), MENG Jun-ping(孟军平), LIANG Guang-chuan(梁广川), WANG Li-juan(王丽娟), ZHANG Jin...-hydrophilic functional ceramic was prepared by adjusting the chemical components of ceramic glaze. Effect of surface free energy of ceramic glaze on oil droplet shape and its behavior in water were......
. This might be due to the fact that the MLGF allowed the free movement of wastewater top surface, while MWSF treated the surface as a horizontal plane. The MLGF described the surface in a more accurate.... 4. The GVF of fluid near aerators was high, and the wastewater close to impellers also contained more volume of gas which might be attributed to the phenomenon that the impellers pushed and stirred......
and low deformability in the as-cast large specimens. More free volume was detected in the smaller as-fractured specimens, by differential scanning calorimetry, which may be attributed to the occurrence... due to their graded structures. Key words: bulk metallic glasses; mechanical behavior; plastic deformation; shear band; free volume 1 Introduction Bulk metallic glasses (BMGs) have aroused extensive......
