| Abstract | Micro-indentation tests at scales on the order of sub-micron have shown that measured hardness increases strongly with decreasing indent depth or indent size, which is frequently referred to as the size effect, In this paper, the micro-indentation experiments for single crystal copper(Cu) and aluminum(Al) are carried out. The experimental results of loading-displacement curves and hardness-depth relations are obtained, which displays the strong size effect. Meanwhile, in order to investigate the micro geometrical size effects, the indentation experiment for material of polycrystal Al is carried out. Finally, the strain gradient plasticity theory is used to model the size effect and geometrical effect for the materials undergoing the micro-indent. The material length parameter is predicted. |
