| 5 | Nanoindentation of soft solids by a fla punch显示文摘Measuring the surface tension and elastic modulus of soft materials and biological tissues under different physiological and pathological conditions is of significanc for understanding various phenomena associated with deformation. In this paper, the nanoindentation of a circular fla punch on a soft solid is analyzed with the influenc of surface tension. By solving the corresponding singular integral equation, the relation between load and indent depth is obtained.When the radius of the fla punch shrinks to the same order as the ratio of surface tension to elastic modulus, surface tension significantl affects the indentation load–depth relation,which provides a facile method to measure surface tension in soft solids and biological tissues. | G.F.Wang X.R.Niu | 2015 | Acta Mechanica Sinica2015，31，4： | 0 |
