对CrMoV与NiCrMoV异种钢焊接接头开展室温及400℃下的高周疲劳试验,并对失效试样进行断口分析,研究异种钢焊接接头的高周疲劳失效机理.结果表明,接头疲劳S-N曲线呈现连续下降形式,在高周疲劳过程中未见疲劳极限平台,失效位置均位于焊缝金属区域,并且集中在显微硬度值最低的结构弱区;随着应力幅值的下降,裂纹萌生模式由表面和内部萌生的竞争转变为内部微缺陷萌生占主导,内部焊接气孔微缺陷是主要裂纹萌生源;根据Murakami模型得到的疲劳极限分散性较大,与高周疲劳寿命未呈现出明显规律,通过引入Z参量模型,指出焊接接头的高周疲劳寿命由应力水平、微缺陷有效尺寸和相对深度等因素共同决定,Z参量与高周疲劳寿命具有很好线性关系.

为了有效模拟3D打印点阵材料夹芯结构在弹丸冲击下的损伤破坏行为,在近场动力学微极模型中引入塑性键,构建了适用于点阵材料夹芯结构的模型和建模方法,在验证模型准确性的基础上,模拟分析了低速和高速弹丸冲击下点阵材料夹芯结构的损伤模式与破坏机理。结果表明:低速冲击下3D打印点阵夹芯结构的破坏模式以局部塑性变形为主;高速冲击下,破坏模式表现为溃裂、孔洞贯穿和碎片喷射,并伴随着大范围的塑性变形。低速冲击下塑性变形范围随冲击速度升高而增大,而高速冲击下则相反。高速冲击下,点阵夹芯结构的贯穿过程分为面板接触、局部屈服、芯材压溃、穿透4个阶段,弹丸经历了急-缓-急3段减速过程,并对应2个加速度高峰,第2个加速度峰值低于第1个加速度峰值的50%;低速冲击过程中,弹丸仅有1次减速过程,加速度峰值随冲击速度的升高而增大,最终弹丸反弹。

Recent advances in organic electronics of novel materials and optoelectronic devices spark great interest in the design and synthesis of high-performance polymer semiconductors. During the last decade, isoindigo(ⅡD) and its derivatives have sprung up as common electron-deficient building blocks and obtained extensive applications in organic field-effect transistors(OFETs).In this review, we first present the current status, basic principles, and general material design strategies for OFETs. Then,multiple ⅡD-type acceptors, mature synthetic routes to monomers, and typical ⅡDs-based conjugated polymers are *** also introduce side-chain engineering and cutting-edge applications, like stretchable transistors, sensing, active-matrix driving, etc., of the classic copolymer poly(isoindigo-co-bithiophene). Green polymerization approaches towards conjugated polymers incorporating ⅡDs are subsequently discussed for efficient polymerization. Finally, we conclude this review and propose in-depth prospects with respect to material synthesis and device applications. Undoubtedly, ⅡDs-based conjugated polymers would occupy a significant position in the future of organic electronics, due to diverse building blocks, mature synthetic pathways, tunable side chains, and unique optoelectronic properties.

索夹是预应力索结构中拉索与其他构件连接的重要节点构件,若索夹和拉索之间发生滑移,会产生较大的预应力损失,甚至改变结构的受力性能。杭州世纪中心西天窗采用箱形桁架+钢索结构,其结构特殊性决定了拉索在施工张拉和施工完成后的状态不同,即施工张拉时要求拉索对索夹是可相对滑移的,而施工完成后需要锁定拉索和索夹的相对位置,不允许发生滑移。通过拉索施工张拉、高强螺栓紧固力衰减、索夹顶推三个阶段的全过程模拟试验确定了索夹与拉索之间的摩擦力情况。试验结果表明,在拉索施工张拉阶段,索夹对索体产生的摩擦力较小,通过锌板垫层能够有效降低铸钢索夹节点处的摩擦损失,保证拉索张拉过程中索力的有效传递;高强螺栓终拧后12h内会产生不可忽视的紧固力损失;使用阶段索夹的抗滑移承载能力能够确保索夹节点安全。
