Finite Element Analysis: PE of an element

  1. Jul 23, 2015 #1
    1. The problem statement, all variables and given/known data
    The potential energy of an element in terms of local displacements q1 and q2 is given by the expression:
    Π = 3(q1^2) - 6q1q2 + 9(q2^2) + 9q1
    Write down the expressions for element stiffness matrix k and element force f.

    I am at a complete loss as to what to do. Please help.
