| Abstract: | Based on the testing theory of indentation hardness,two-dimensional axisymmetric finite element model was established.The pressing process of the pure titanium under the loading,as well as the stress distribution and yield region around the indentation in the indentation hardness test process were analyzed by the finite element method.Moreover largest pressing depth was obtained by the load displacement curves,thereby ball hardness was calculated. |
| Keywords: | indentation hardness finite element analysis stress distribution |
