J. Cent. South Univ. (2019) 26: 1830-1839 DOI: https://doi.org/10.1007/s11771-019-4137-0 Nested Newmark model to estimate permanent displacement of seismic slopes with tensile strength cut-off ZHOU... shear movements. The original NNM omits that the tensile stresses would be encountered in slopes induced by earthquakes. The purpose of this study is to introduce the tensile strength cut-off......
J. Cent. South Univ. (2016) 23: 1839-1846 DOI: 10.1007/s11771-016-3238-2 Correlation between microstructural features and tensile strength for friction welded joints of AA-7005 aluminum alloy Seyyed...). Microstructural observations reveal the formation of intermetallic phases during the welding process which cannot be extruded from the interface. Theses phases influence the tensile strength of the resultant......

J. Cent. South Univ. (2020) 27: 2148-2159 DOI: https://doi.org/10.1007/s11771-020-4437-4 Active earth pressure for subgrade retaining walls in cohesive backfills with tensile strength cut-off...-C) failure condition has a limitation that it overestimates the tensile strength of cohesive soils. To overcome this limitation, the tensile strength cut-off was applied where the predicted tensile......
Establishing empirical relationships to predict grain size and tensile strength of friction stir welded AA 6061-T6 aluminium alloy joints S. RAJAKUMAR, C. MURALIDHARAN, V. BALASUBRAMANIAN.... Joint strength is influenced by the grain size and tensile strength of the weld nugget region. Hence, an attempt was made to develop empirical relationships to predict grain size and tensile......
