Get the stress tensor using virtual displacement principle

  1. Jun 26, 2012 #1
    The problem statement, all variables and given/known data
    Using method of virtual displacement get the stress tensor for this problem.

    The attempt at a solution

    The given system is 4-times tatically indeterminate. Since it is symetrical we can split it in half vertically. We need to fix it in one point (upper end). The "new" system is 3-times statically indeterminate.

    As far as I know we need to split this into several systems; 1 main + 3 virtual. But I don't really know how and which variables do I need to have. I do not seek the answer to the whole problem (calculating when we get these variables), just some help on how to split this further.

    Any help appritiated, thank you!

    And I am sorry if I used some expressions that are not correct, english is not my main language. :)
