| 1 | 铝合金非承载十字接头疲劳特性显示文摘基于结构应力法,计算拉伸疲劳加载时不同几何尺寸的7N01铝合金非承载十字接头的结构应力,并结合疲劳试验数据建立其疲劳失效的主S-N曲线.结果表明,与名义应力法相比,基于结构应力法的主S-N曲线线性相关性更好,能够适应不同几何尺寸十字接头疲劳的计算.进一步分析相同名义应力下,承载板厚度对疲劳寿命的影响,结果表明,接头疲劳承载能力的增加与板厚的增加并非线性关系,随着承载板厚度增加,接头疲劳寿命降低. | 刘永 王苹 马然 Pingsha Dong 方洪渊 | 2016 | 焊接学报2016，37，8： | 5 |
| 2 | 焊接结构抗疲劳设计新方法与应用显示文摘与传统金属材料/小尺寸疲劳试样不同,焊接结构具有其独特的疲劳特性:裂纹萌生周期短、疲劳寿命主要消耗在裂纹扩展阶段、焊接结构疲劳具有尺寸效应,这些因素导致了动载荷应力幅值为焊接结构疲劳失效的第一驱动力。基于有限元分析的无网格敏感性结构应力法,可有效描述焊接接头位置的动载荷应力。该方法结合国际疲劳设计标准中S-N曲线族与裂纹扩展速率关系,提出一条能够统一描述不同几何形式、不同板厚接头疲劳行为的Master S-N曲线。该方法在2003年SAE'Fatigue Challenge'焊接结构疲劳预测挑战中获得最准确的结果,并已纳入ASME FFS-1标准等国际标准。结构应变方法则是在结构应力方法基础上提出,可以进一步统一描述不同材料焊接构件的高/低周疲劳性能的疲劳评估方法。该方法采用Master E-N曲线将高周疲劳与低周疲劳分析方法统一。目前此方法已经应用于轨道交通、正交异性桥、重型装备等大型复杂焊接结构的疲劳设计与服役寿命预测中,可量化分析焊接变形、焊缝尺寸、熔透率等因素的影响,实现针对复杂焊接结构/接头的抗疲劳设计。 | 王苹 裴宪军 钱宏亮 DONG Pingsha | 2021 | 机械工程学报2021，57，16： | 5 |

| 5 | 3D printing of fine-grained aluminum alloys through extrusion-based additive manufacturing:Microstructure and property characterization显示文摘Additive manufacturing(AM)has the potential to transform manufacturing by enabling previously un-thinkable products,digital inventory and delivery,and distributed manufacturing.Here we presented an extrusion-based metal AM method(refer to“SoftTouch”depositionin thefiledpatent)thatis suitablefor making the metal feedstock flowable prior to the deposition through dynamic recrystallization induced grain refinement at elevated temperatures.The flowable metal was extruded out of the printer head like a paste for building dense metal parts with fine equiaxed grains and wrought mechanical properties.Off-the-shelf metal rods were used as feedstock and the printing process was completed in an open-air environment,avoiding pricy powders and costly inert or vacuum conditions.The resulting multi-layer de-posited 6061 aluminum alloys yield strength and ductility comparable to wrought 6061 aluminum alloys after the same T6 heat treatment.The extrusion-based metal AM method can also be advanced as green manufacturing technologies for fabricating novel alloys and composites,adding novel features to existing parts,repairing damaged metal parts,and welding advanced metals for supporting sustainable manufac-turing,in addition to being developed into a cost-effective manufacturing process for the fabrication of dense metal of complex structural forms. | Fengchao Liu Pingsha Dong Abdul Sayeed Khan Yuning Zhang Randy Cheng Alan Taub Zongyi Ma | 2023 | Journal of Materials Science & Technology2023，，8： | 1 |

| 13 | Environmental and economic benefit of recycling model of packaging waste:a case study on aluminum显示文摘In order to achieve sustainable utilization of natural resources, save energy and protect environment and ecosystem, it is important for a region or a nation to develop and implement a viable waste recycling model from both theoretical and practical point of view. Some packaging recycling models operated in developed countries are introduced in this article. Aluminium can recovery and recycling is emphasized. Cost effective, economic and environmental benefit of different models are compared and analyzed. The result shows that all recycling models have their characteristics due to the initial purpose of recovery and the situation of the implementing country. However, all the models contribute to the reduction of municipal solid waste disposal and resources conservation. | Huang Pingsha Department of Environmental Science, Zhejiang Wanli University, Ningbo 315100, China | 2004 | Chinese Journal of Population,Resources and Environment2004，2，3： | 0 |
