A New Stress Field Model for Semiclosed Crack under Compression considering the Influence of T-Stress by Mingyu Feng, Xiaoguang Zhou, Yanbin Zhang, Saifeng Wu

“…To reflect the actual state of crack, a comprehensive stress field model around the semiclosed crack is established based on the complex potential theory, and the stress intensity factor KII at the crack tip related to the closure amount of crack surfaces, deep-water pressure, friction coefficient in the closed region, and crack inclination angle is derived. The analytical solution of the stress field around the semiclosed crack contains three T-stress components, i.e., Tx, Ty, and Txy. …”

Les rendez-vous manqués de l’ethnologie et de la primatologie de terrain (1960-2010) by Vincent Leblan

“…The ambition of a primate societies ethnography presently called for in ethology is then examined under two different angles:for one part, by tracing the unrecognized descent of the use of the culture concept in primatology to American (USA) cultural anthropologists’ comments on anthropoid psychology during the interwar years, while this invention is often traced exclusively to Japanese primatology in the postwar years. …”

Semiactive Control of High-Speed Railway Vehicle Suspension Systems with Magnetorheological Dampers by Yingying Liao, Yongqiang Liu, Shaopu Yang

“…The railway vehicle is modeled by a 50 degree-of-freedom (DOF) system which considers the full 6 DOF of each wheelset, bogie, car body, and the pitch angle of each axle box. Several control strategies, sky-hook (SH), acceleration-driven damping (ADD), and mixed SH-ADD, are considered in the semiactive suspension system. …”

Abnormal Grain Growth Mechanism in the Twin-Roller Cast Al-Fe-Si Alloy in the Annealing Process by Y. Z. Zhu, H. Peng, H. Huang, J. C. Li

“…The growth of abnormal grain was governed by the coalescence of the abnormal grain with its surrounding normal grains, with an average orientation angle of 47° between both the types of grains. High-strain-concentrated regions on the surface layer of the billet were induced by the heterogeneously distributed Fe particles formed in the twin-roller casting process. …”
