TENSILE STRENGTH AND CREEP RESISTANCE OF Mg-9Al-1ZnBASED ALLOYS WITH CALCIUM ADDITION Y.S.Sun1,W.M.Zhang1,X.G.Min1 (1.Department of Materials Science and Engineering, Southeast University, Nanjing...:tensile strength magnesium alloy; calcium; creep resistance; [全文内容正在添加中] ......
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......
study based on blind data theory and fuzzy interval estimation. 60 granite specimens are first tested, the compressive strength interval and tensile strength interval are [103.68, 219.61] and [7.53, 11.86] MPa, while the tested mean values of compressive strength and tensile strength are 152.86 and 10.14 MPa, the credibilities are less than 58.4% and around 70.4%, respectively, the credibility......
Influence of La-Ce Mischmetal on Dendritical Arm Space and Ultimate Tensile Strength in ZL105 Alloys LI Ge-sheng1,LI Hua-ji1,LIU Chang-ming1 (1.Department of Mechanical Engineering, Chongqing... of adding amount of (La+Ce) mischmetal on LDAS and ultimate tensile strength(σb) were investigated, and the relationship between σb and LDAS was founded. (La+Ce) mischmetal has stronger ability to refine......

Influence of yield-to-tensile strength ratio (Y/T) on failure assessment of defect-free and corroded X70 steel pipelineZHANG Shun-hu(章顺虎)1, 2, ZHAO De-wen(赵德文)1, WANG Xiao-nan(王晓南)2(1. State Key... corrosion defects is a function of the Y/T, pipe geometry t0/D0 and engineering tensile strength, and increases as Y/T or t0/D0 increases; whilst the burst pressure of corroded X70 pipe decreases......
