Triaxial Test and Mechanical Analysis of Rock-Soil Aggregate Sampled from Natural Sliding Mass by Shuling Huang, Xiuli Ding, Yuting Zhang, Wei Cheng

“…Further, the influences of stone content, and gradation variation on stress-strain curve, Mohr-Coulomb criterion based shear strength parameters, Duncan-Chang model based deformation parameters, and internal friction angle are analyzed. A modified Rowe’s stress-dilatancy equation describing the mechanical response of rock-soil aggregate is then suggested.…”

Parkinsonian Rigidity Depends on the Velocity of Passive Joint Movement by Takuyuki Endo, Naoya Yoshikawa, Harutoshi Fujimura, Saburo Sakoda

“…The elbow joints of 20 Parkinson’s disease patients were passively flexed and extended, and two characteristic values, the elastic coefficient (elasticity) and the difference in bias (difference in torque measurements for extension and flexion), were identified from a plot of the angle and torque characteristics. Flexion and extension were done at two different velocities, 60°/s and 120°/s, and a statistical analysis was performed to determine whether the changes in these characteristic values were velocity-dependent. …”

The surface of non-linear rotation by K. L. Panchuk, T. M. Myasoyedova

“…It is known that in Euclidean geometry and mechanics the transformation of rotation is linear, while distance and angle are its invariants. The authors proposed a geometric scheme of non-linear rotation, in which the axis of rotation is a smooth spatial curve and the object of rotation is a smooth line. …”

Research on Carrying Capacity of T-Shaped Stiffened Concrete-Filled Steel Tubular Columns Subjected to Eccentrically Compressive Load by Yuanlong Yang, Xinchen Han, Bo Nan, Xin Tang

“…A parametric analysis was carried out to calculate M-N correlation curves of cross section and column to investigate influence of concrete strength fck, steel yielding strength fy, steel tube thickness t, slenderness ratio λ, and loading angle θ. On the basis of parametric analysis, simplified resistance models of T-shaped CFST section and column were proposed and verified by the numerical analysis results. …”

Structural Evolution of Low-Molecular-Weight Poly(ethylene oxide)-block-polystyrene Diblock Copolymer Thin Film by Hui Wu, Xiaohua Huang

“…The structural evolution of low-molecular-weight poly(ethylene oxide)-block-polystyrene (PEO-b-PS) diblock copolymer thin film with various initial film thicknesses on silicon substrate under thermal annealing was investigated by atomic force microscopy, optical microscopy, and contact angle measurement. At film thickness below half of the interlamellar spacing of the diblock copolymer (6.2 nm), the entire silicon is covered by a polymer brush with PEO blocks anchored on the Si substrate due to the substrate-induced effect. …”

Bank collapse-landslide failure mechanism of typical reverse rock bank slope in Three Gorges Reservoir area by Yang LI, Hailin ZHAO, Bolin HUANG, Honglin LI, Kaikai XU

“…At present, most of the reverse rock slope toppling instability failure is interpreted as a progressive overall instability failure controlled by dip angle and structural plane. However, the phenomenon of leading edge collapse is common in some reservoir areas before the toppling deformation of reverse rock slope is intensified or destabilized. …”

Hydro-mechanical behavior of two clayey soils in presence of household waste leachates by H. Yonli, B. François, D. Toguyeni, A. Pantet

“…For soils from Nouna, the effective cohesion increases from 3 to 21 kPa with a slight decrease of friction angle; for soils from Boudry a slight increase of cohesion is noticed while friction angle increases from 34 to 37°.CONCLUSIONThis comparative study is of practical use to environmental geotechnics professionals because it shows that the choice in designing a bottom liner must be a compromise between long term hydraulic and mechanical behaviors of soils. …”
