    Problem with large deformation

    Dear all, When I am simulating the indentation with large displacement and I found that the model cannot be solve. Although I have follow what the error message told me: 1) increase the FKN or FTOL; 2) increase the number of substep However, it didn't help. I would like to ask it is the...

    Problem of indentation with axisymmetry

    harry, I have found that there is no need to mulitple the value with 2 pi as the reaction force i have got is the total one. Thank you very much for you help. Jeff

    Problem of indentation with axisymmetry

    Dear all, I am doing a simulation of nanoindentation. I have setup a axisymmetry model in which a indenter press onto a specimen with displacement. I have couple nodes so that I can obtain the reaction force. However, while I compare the data with Hertzian analysis, I found that they are not...
