中文摘要:

为嵌入的碳 nanotubes 的弄弯的分析由像挑出的模型的应用程序激发了, orthotropic 像挑出的模型被开发在细胞质以内学习嵌入的细胞骨架微导管的弄弯的行为。弄弯嵌入的细胞骨架微导管的试验性的观察表明嵌入的微导管作为与免费微导管相比忍受大压缩力量。现在的理论模型预言在有弹性的媒介的嵌入的微导管比免费微导管忍受大压缩力量。估计的批评压力在对微导管的导致压力的弄弯的试验性的价值的好同意。而且由于与包围有弹性的媒介的微导管的机械联合,批评弄弯力量更加被增加,它井向与有弹性的媒介的微导管的机械联合增加的理论解释微导管能支撑的压缩力量。在纸介绍的模型是为嵌入的微导管的弄弯的分析的好近似。

英文摘要:

Motivated by the application of Winkler-like models for the buckling analysis of embedded carbon nanotubes, an orthotropic Winkler-like model is developed to study the buckling behavior of embedded cytoskeletal microtubules within the cytoplasm. Experimental observations of the buckling of embedded cytoskeletal microtubules reveal that embedded microtubules bear a large compressive force as compared with free microtubules. The present theoretical model predicts that embedded microtubules in an elastic medium bear large compressive forces than free microtubules. The estimated critical pressure is in good agreement with the experimental values of the pressure-induced buckling of microtubules. Moreover, due to the mechanical coupling of microtubules with the surrounding elastic medium, the critical buckling force is increased considerably, which well explains the theory that the mechanical coupling of microtubules with an elastic medium increases compressive forces that microtubules can sustain. The model presented in the paper is a good approximation for the buckling analysis of embedded microtubules.
