| 1 | 基于粘聚区模型的电阻点焊搭接失效模拟(英文)显示文摘本文主要研究电阻点焊(RSW)连接薄壁单搭接头在拉伸载荷作用下的断裂过程。对3组不同节点结构的搭接头进行试验,以获得接头的拉伸性能。为了模拟焊接接头的拉伸行为,首先采用二维轴对称有限元模型计算焊接过程中产生的残余应力,然后将结果转化为三维模型作为预应力。在此基础上,采用粘聚区模型(CZM)对拉伸载荷作用下模型中的断裂进行数值模拟。采用拉皮法和剪切搭接法提取粘聚区参数。用于模拟单搭接点焊试样的变形和失效的结果表明,在模拟变形和断裂载荷时,考虑残余应力的影响对保证预测结果的准确性是必要的。 | Mohammad Ali Saeimi SADIGH Gholamreza MARAMI Bahman PAYGOZAR | 2018 | Journal of Central South University2018，25，11： | 5 |
| 2 | 一种新型的轴向载荷作用下的混合吸能机制(英文)显示文摘本研究结合两种常见的机制以提高系统吸收移动车辆或设备动能的能力。该模型由两个独立的机制组成,即圆管的膨胀和内胎的破碎,通过内胎的摩擦、塑性变形和失效来耗散能量。本研究调查24个在恒质量和恒体积两种不同设计控制下的案例以进行比较。利用有限元模拟方法研究了模型的变形,提取了耐撞性参数,以反映机制的效率,并对三种不同的内胎外形进行了参数化研究。研究表明,内环型和六角形管型模型由于经历了折叠、剪切和延性损伤三种不同的能量耗散系统,吸收了更多的能量。 | BAHMAN Paygozar MOHAMMAD ALI Saeimi Sadigh | 2020 | Journal of Central South University2020，27，1： | 2 |

| 14 | Regulation of cell survival and death during Flavivirus infections显示文摘Flaviviruses, ss(+) RNA viruses, include many of mankind's most important pathogens. Their pathogenicity derives from their ability to infect many types of cells including neurons, to replicate, and eventually to kill the cells. Flaviviruses can activate tumor necrosis factor α and both intrinsic(Bax-mediated) and extrinsic pathways to apoptosis. Thus they can use many approaches for activating these pathways. Infection can lead to necrosis if viral load is extremely high or to other types of cell death if routes to apoptosis are blocked. Dengue and Japanese Encephalitis Virus can also activate autophagy. In this case the autophagy temporarily spares the infected cell, allowing a longer period of reproduction for the virus, and the autophagy further protects the cell against other stresses such as those caused by reactive oxygen species. Several of the viral proteins have been shown to induce apoptosis or autophagy on their own, independent of the presence of other viral proteins. Given the versatility of these viruses to adapt to and manipulate the metabolism, and thus to control the survival of, the infected cells, we need to understand much better how the specific viral proteins affect the pathways to apoptosis and autophagy. Only in this manner will we be able to minimize the pathology that they cause. | Sounak Ghosh Roy Beata Sadigh Emmanuel Datan Richard A Lockshin Zahra Zakeri | 2014 | World Journal of Biological Chemistry2014，5，2： | 1 |
