Isoparametric Formulation; it's elementary, really

  1. Feb 11, 2015 #1
    1. The problem statement, all variables and given/known data
    Use the isoparametric formulation to express the following deflection information: U1=0.01cm, U2=0.025 cm with the corresponding global coordinates X1=5cm, X2=12cm
    Show the transformation equations between the global coordinate, the local coordinate, and the natural coordinate

    2. Relevant equations
    I really wish I knew.

    3. The attempt at a solution
    I've been confused, oblivious, and completely ignorant enough times that it could be a certifiable miracle I'm a graduate student today, but I cannot recall a time I've been this derailed. I don't even know what this question is asking. If someone could even just be like, "hey do this to get started," I'd be in your debt. I have two textbooks supposedly on this information and neither of them identify what I'm looking at here.
