| 1 | Experimental and simulation optimization analysis of the Whipple shields against shaped charge显示文摘Occasionally,the Whipple shields are used for the protection of a space station and a satellite against the meteoroids and orbital debris.In the Whipple shields each layer of the shield depletes part of high speed projectile energy either by breaking the projectile or absorbing its energy.Similarly,this investigation uses the Whipple shields against the shaped charge to protect the light armour such as infantry fighting vehicles with a little modification in their design.The unsteady multiple interactions of shaped charge jet with the Whipple shield package against the steady homogeneous target is scrutinized to optimize the shield thickness.Simulations indicate that the shield thickness of 0.75 mm offers an optimum configuration against the shaped charge.Experiments also support this evidence. | G.Hussain A.Hameed I.Horsfall P.Barton A.Q.Malik | 2012 | Acta Mechanica Sinica2012，28，3： | 4 |
| 2 | Formability of Materials with Small Tools in Incremental Forming显示文摘Single point incremental forming(SPIF)is an innovative sheet forming process with a high economic pay-off.The formability in this process can be maximized by executing forming with a tool of specific small radius,regarded as threshold critical radius.Its value has been reported as 2.2 mm for 1 mm thick sheet materials.However,with a change in the forming conditions specifically in the sheet thickness and step size,the critical radius is likely to alter due to a change in the bending condition.The main aim of the present study is to undertake this point into account and develop a relatively generic condition.The study is composed of experimental and numerical investigations.The maximum wall angle(θmax)without sheet fracturing is regarded as sheet formability.A number of sheet materials are formed to fracture and the trends correlating formability with normalized radius(i.e.,R/To where R is the tool-radius and To is the sheet thickness)are drawn.These trends confirm that there is a critical tool-radius(Rc)that maximizes the formability in SPIF.Furthermore,it is found that the critical radius is not fixed rather it shows dependence on the sheet thickness such that Rc=βTo,whereβvaries from 2.2 to 3.3 as the thickness increases from 1 mm to 3 mm.The critical radius,however,remains insensitive to variation in step size ranging from 0.3 mm to 0.7 mm.This is also observed that the selection of tool with R | Hongyu Wei G.Hussain X.Shi B.B.L Isidore Mohammed Alkahtani Mustufa Haider Abidi | 2020 | Chinese Journal of Mechanical Engineering2020，33，4： | 1 |
| 3 | 渐进成形圆柱孔翻边的有限元和实验分析(英文)显示文摘研究单点渐进成形中坯料预切孔尺寸对圆柱孔翻边的可成形性的影响。翻边制造从45°到90°分为4个阶段,采用铝作为实验材料。孔尺寸对圆柱翻边的应力/应变分布有显著影响。随着孔尺寸的增大周向应变增大,翻边的壁厚增厚。同样地,随着孔尺寸的增大von Mises应力降低。而且,孔尺寸存在一个临界值(80 mm),当低于这个值时会产生严重的应力,从而导致板材断裂,圆柱翻边成形失败。随着孔尺寸的减小,且大于临界尺寸时,可成形性降低。结果表明,孔的临界尺寸为80 mm能使铝板在渐进孔成形中的可成形性能最大化。 | G.HUSSAIN H.VALAEI Khalid A.Al-GHAMDI B.KHAN | 2016 | Transactions of Nonferrous Metals Society of China2016，26，9： | 1 |
| 4 | 核孔膜测定溶液浓度的原理、实验及应用前景显示文摘用实验证明,核孔膜可以用来测定溶液浓度,即测定溶液中溶质的含量。这一发展,为核孔膜在工业上广泛应用开辟了新的领域。本文对用核孔膜测定溶液浓度的原理、方法、精确度、适用范围和应用前景进行阐述。 | 郭士伦 王玉兰 郝秀红 樊中钧 朱天成 H.A.Khan G.Hussain R.Brandt P.Vater | 1992 | 原子能科学技术1992，26，4： | 1 |
| 5 | 渐进成形冷固结多层覆铜板的鼓包:成形条件和弯曲的影响(英文)显示文摘鼓包是渐进成形工艺(ISF)中引起几何误差和过早失效的一种缺陷。本研究的目的是:(1)了解覆铜三层钢板的鼓包行为与成形条件之间的关系;(2)分析弯曲对鼓包的影响,并试图得出相关机理。为此,进行一系列的渐进成形和弯曲实验。结果表明:层状板材的鼓包形成对成形条件较敏感,可以通过采用退火材料,更大的刀具直径和步长进行ISF加工,使鼓包减到最小,弯曲分析表明,鼓包是成形工具在ISF过程中施加在板材上的弯曲力矩作用的结果;当力矩从0.046增加到10.24 N·m/m时,鼓包的平均高度从0.07增加到0.91 mm;层状板材中的鼓包与弯曲力矩呈线性关系。综上,通过控制弯曲力矩可以克服鼓包缺陷,本研究提出的公式对相关研究有一定的帮助。 | Khalid A.AL-GHAMDI G.HUSSAIN | 2019 | Transactions of Nonferrous Metals Society of China2019，29，1： | 1 |
| 6 | Improved measurement of the reactor antineutrino flux and spectrum at Daya Bay显示文摘A new measurement of the reactor antineutrino flux and energy spectrum by the Daya Bay reactor neutrino experiment is reported. The antineutrinos were generated by six 2.9 GWth nuclear reactors and detected by eight antineutrino detectors deployed in two near(560 m and 600 m flux-weighted baselines) and one far(1640 m flux-weighted baseline) underground experimental halls. With 621 days of data, more than 1.2 million inverse beta decay(IBD) candidates were detected. The IBD yield in the eight detectors was measured, and the ratio of measured to predicted flux was found to be 0.946±0.020(0.992±0.021) for the Huber+Mueller(ILL+Vogel) model. A 2.9σ deviation was found in the measured IBD positron energy spectrum compared to the predictions. In particular, an excess of events in the region of 4–6 MeV was found in the measured spectrum, with a local significance of 4.4σ. A reactor antineutrino spectrum weighted by the IBD cross section is extracted for model-independent predictions. | 安丰鹏 A.B.Balantekin H.R.Band M.Bishai S.Blyth 曹德文 曹国富 曹俊 岑吴镕 陳日朗 常劲帆 張立楚 张昀 陈和生 陈泉佑 陈少敏 陈义学 陈羽 程佳樺 程捷 程雅苹 成兆侃 J.J.Cherwinka 朱明中 A.Chukanov J.P.Cummings J.de Arcos 邓子艳 丁雪峰 丁雅韵 M.V.Diwan M.Dolgareva J.Dove D.A.Dwyer W.R.Edwards R.Gill M.Gonchar 龚光华 宫辉 M.Grassi 顾文强 关梦云 郭磊 郭如盼 郭新恒 郭子溢 R.W.Hackenburg 韩然 S.Hans 何苗 K.M.Heeger 衡月昆 A.Higuera Y.K.Hor 熊怡 胡貝禎 胡涛 胡维 黄恩泉 黄翰雄 黄性涛 P.Huber 霍文驹 G.Hussain D.E.Jaffe P.Jaffke 任國綸 S.Jetter 季向盼 季筱璐 焦健斌 R.A.Johnson D.Jones J.Joshi 康丽 S.H.Kettell S.Kohn M.Kramer 關健强 郭文伟 郭天能 T.J.Langford K.Lau L.Lebanowski J.Lee 李曉菁 雷瑞庭 R.Leitner 李超 李登杰 李飞 李高嵩 李秋菊 黎山峰 S.C.Li 李卫东 李小男 李玉峰 李志兵 梁昊 林政儒 林贵林 林盛鑫 林士凱 林禹丞 凌家杰 J.M.Link L.Littenberg B.R.Littlejohn 刘大为 刘江来 刘金昌 C.W.Loh 陆昌国 路浩奇 陆稼书 陆锦标 吕志鹏 马秋梅 马晓妍 马续波 马宇倩 Y.Malyshkin D.A.Martinez Caicedo K.T.McDonald R.D.McKeown I.Mitchell M.Mooney Y.Nakajima J.Napolitano D.Naumov E.Naumova 倪浩然 宁哲 J.P.Ochoa-Ricoux A.Olshevskiy 潘孝儒 J.Park S.Patton V.Pec 彭仁杰 L.Pinsky 潘振声 齐法制 祁鸣 钱鑫 N.Raper 任杰 R.Rosero B.Roskovec 阮锡超 H.Steiner 孙功星 孙吉良 唐炜 D.Taychenachev K.TVeskov K.V.Tsang C.E.Tull N.Viaux B.Viren V.Vorobei 王正祥 王萌 王乃彦 王瑞光 王为 王玺 王贻芳 王喆 王铮 王志民 魏瀚宇 温良剑 K.Whisnant C.G.White L.Whitehead T.Wise 黄显诺 黄振辉 E.Worcester 吳珈豪 吴群 吴文杰 夏冬梅 夏经凯 邢志忠 徐建一 徐吉磊 徐晔 薛涛 杨长根 杨海波 杨雷 阳马生 杨梦婷 叶梅 Z.Ye 叶铭芳 杨炳麟 于泽源 曾珊 占亮 张超 张宏浩 张家文 张清民 张玄同 张一鸣 张一心 张玉美 张志坚 张智勇 张子平 赵洁 赵庆旺 赵豫斌 钟玮丽 周莉 N.Zhou 庄红林 邹佳恒 | 2017 | Chinese Physics C2017，41，1： | 0 |
