| 1 | 铝合金材料AA-6061-T6和AA-6061-OA的动态拉伸力学性能(英文)显示文摘铝合金材料蜂窝夹层板结构具有在较低体重情况下的高硬度和高抗冲击性能力。近年来许多关于其在低应变率下冲击能量吸收性质的文献纷纷涌现,但是对于其在高应变率下的能量吸收力学性能的研究却非常贫乏。为了更好地研究铝合金材料蜂窝夹层板结构在高应变率下的能量吸收力学性能,其结构组成材料本身的动态力学性能必须首先得到充分研究。本文介绍和总结了铝合金材料AA-6061的两种热处理成品,T6与OA,在室温(24℃)与低温( -170℃)下的动态拉伸力学性能。在本研究中,霍普金生拉伸杆被应用,拉伸应变率为103每秒。 | 唐欣 Vikas Prakash John Lewandowski | 2007 | 实验力学2007，22，3： | 7 |

| 10 | Numerical analysis of hemodynamic parameters in stenosed arteries under pulsatile flow conditions显示文摘This research studies the changes in flow patterns and hemodynamic parameters of diverse shapes and sizes of stenosis.Six different shapes and sizes of stenosis are constructed to investigate the variations in hemodynamics as the morphology changes.Changes in shape(trapezoidal and bell-shaped)and sizes of stenosis change the stresses on the walls and their flow patterns.TAWSS and OSI results specify that trapezoidal stenosis exerts greater stress than bell-shaped stenosis.Also,as the length of the trapezoidal stenosis increases,the TAWSS increases,whereas the trend is the opposite for bell-shaped stenosis.Later,this paper also studies different degrees of stenosis extracted from real images.Changes in velocity flow patterns,wall shear stress(WSS),Time-averaged wall shear stress(TAWSS)and Oscillatory shear index(OSI)have been studied for these images.Results illustrate that the peak velocity rises drastically as the stenosis percentage increases.Negative velocity is seen close to the artery's walls,indicating flow separation.This flow separation region is seen throughout the cycle except in the accelerating flow region.An increase in stenosis also increases WSS and TAWSS drastically.Negative WSS is seen downstream of stenosis,indicating flow recirculation.Such negative WSS in the blood vessels also promotes endothelial dysfunction.OSI values greater than 0.2 are seen near the stenosis region,indicating atherosclerosis growth.Regions of high OSI and low TAWSS are also identified,indicating probable regions of plaque development. | Priyambada Praharaj Chandrakant Sonawane Anand Pandey Vikas Kumar Arundhati Warke Hitesh Panchal R.Ibrahim Chander Prakash | 2023 | Medicine in Novel Technology and Devices2023，，4： | 0 |
| 11 | Studies on induction hardening of powder-metallurgy-processed Fe–Cr/Mo alloys显示文摘Induction hardening of dense Fe–Cr/Mo alloys processed via the powder-metallurgy route was studied. The Fe-3Cr-0.5Mo, Fe-1.5Cr-0.2Mo, and Fe-0.85 Mo pre-alloyed powders were mixed with 0.4wt%, 0.6wt%, and 0.8wt% C and compacted at 500, 600, and 700 MPa, respectively. The compacts were sintered at 1473 K for 1 h and then cooled at 6 K/min. Ferrite with pearlite was mostly observed in the sintered alloys with 0.4wt% C, whereas a carbide network was also present in the alloys with 0.8wt% C. Graphite at prior particle boundaries led to deterioration of the mechanical properties of alloys with 0.8wt% C, whereas no significant induction hardening was achieved in alloys with 0.4wt% C. Among the investigated samples, alloys with 0.6wt% C exhibited the highest strength and ductility and were found to be suitable for induction hardening. The hardening was carried out at a frequency of 2.0 kHz for 2–3 s. A case depth of 2.5 mm was achieved while maintaining the bulk(interior) hardness of approximately HV 230. A martensitic structure was observed on the outer periphery of the samples. The hardness varied from HV 600 to HV 375 from the sample surface to the interior of the case hardened region. The best combination of properties and hardening depth was achieved in case of the Fe-1.5Cr-0.2Mo alloy with 0.6wt% C. | Sandeep Chauhan Vikas Verma Ujjwal Prakash P.C.Tewari Dinesh Khanduja | 2017 | International Journal of Minerals,Metallurgy and Materials2017，24，8： | 0 |
