with shear modulus increasing following an exponential function with depth CHEN Changfu, TANG Yu, LIANG Guanting (Geotechnical Engineering Institute, Hunan University, Changsha 410082, China) Abstract: Considering the characteristics of mechanical properties of the ground soil varying with depth, it is assumed that soil’s shear modulus, shear strength in the elastic limit state and residual coefficient......
. The compressive behavior and energy absorption characteristics of MPPC were investigated and compared with the aluminum foams. The compressive modulus of composite was compared with the VOIGT–REUSS bounds and HASHIN-SHTRIKMAN (H-S) bounds models. The experimental modulus of compressive tests falls well within the theoretical models. Key words: MPPC composite; microstructure; compressive behavior......
(Yangtze River Scientific Research Institute), Wuhan 430010, China)Abstract:The relationship among the surface fissure ratio, moisture content, seepage coefficient and deformation modulus of field... among the surface fissure ratio, moisture content, seepage coefficient and deformation modulus was initially established. The surface fissure ratio and moisture content show a linear relation, "y......
using radius-displacement-dependent deformation modulus (RDDM) was proposed. Considering the nonlinearity characteristic of deformation and locality otherness of surrounding rock, deterioration parameter field of deformation modulus of rockmass around opening was quantitatively calculated through a given function. Applicability for multi-cavern condition and parameter sensibility of the model......
Institute for Nonferrous Metal Research, Xi’an 710016, China) Abstract: The phase transformation and the effect of metastable phase on the strength and elastic modulus of the Ti3Zr2Sn3Mo25Nb alloy were... on the strength, elastic modulus and plasticity of the alloy. The smaller the size, the more the quantity and the more equally the distribution of the ω phase, which are of benefit to increasing......
