Abstract: Microtubules (MTs) play a central role in various cell mechanics problems of current interest. In this presentation, some physical phenomena of microtubule mechanics will be introduced, and several new elastic models developed recently will be presented to study microtubule mechanics problems. Among others, for example, critical pressure predicted by an orthotropic elastic shell model for buckling of microtubules under radial pressure is found to be in good agreement with recent experiments which cannot be explained by a previous isotropic model, and the present models give a plausible explanation for the observed length-dependent flexural rigidity of microtubules which has raised a debate in the literature. The results suggest that the elastic models have the potential to be used for studying mechanical behavior of microtubules in cell mechanics.
Brief CV: Dr. Ru is currently a Professor in department of mechanical engineering, University of Alberta, Canada. Dr. Ru received his doctorate in solid mechanics at Peking University, China. After then, Dr. Ru worked in the Institute of Mechanics, Chinese Academy of Science, and held a number of visitor/research positions in several universities in Italy, USA and Canada. He joined the University of Alberta as a faculty member in 1997. Dr. Ru’s past research areas include plastic buckling of structures, mechanics of elastic inclusions, electroelastic mechanics, and some applied mathematics problems related to solid mechanics. His recent research interest focuses on solid mechanics at micro/nano scale, mechanics of carbon nanotubes, and cell mechanics.
