  Effect of dynamic loading on ductile crack initiation behaviour of notched specimen with strength mismatch

  摘要：

  本研究采用基于等效塑性应变和应力三轴性的双参数准则，重点研究了几何不连续性、强度不匹配（可因异质塑性应变而增加塑性约束）以及加载速率对韧性断裂起始临界条件的影响。在动态加载条件下，使用圆周缺口弯曲试样进行了断裂萌发测试。为了评估试样中韧性裂纹萌发状态的条件，进行了热弹性/塑性动态有限元分析，考虑了塑性变形引起的温度升高。结果表明，在动态弯曲加载条件下，双参数准则适用于从强度不匹配试样的预缺口根部表面开始的延性开裂。

  New approach to the synthesis of star-shaped polymers based on calix[8]arene with amphiphilic arms of nonionogenic nature is described. The ionophore properties of the resulting polymer with respect to ions of alkali metals, europium, and uranium were studied by an example of a polymer containing residues of omega-cetyloligoethylene oxide as arms.

  Two neutral star-shaped polymers with calix[8]arene core and eight amphiphilic alkyloligoethyleneoxide arms have been synthesised using the arm-first approach. One of them has arms with oligoethylene oxide block attached to the calix[8]arene core, whereas the other one has arms where the oligoethylene oxide is the outer block. Both polymers are soluble in most common organic solvents and form true, i.e., molecularly dispersed solutions. In highly dilute aqueous solutions these polymers form loose multi-molecular clusters, which do not disintegrate upon further dilution but break in a shear flow. Aggregation of these star polymers in water is investigated using light scattering and the structure of the aggregates is discussed. The ability of the stars to bind a series of metal ions and the effectiveness of these polymers as phase-transfer agents were investigated in respect to their molecular architecture. The performance of the star-shaped polymers was also compared to that of crown ethers. (C) 2010 Elsevier Ltd. All rights reserved.
