    PDE in Matlab

    Hallo all, I'm working on solving a set of PDEs, and try to make use matlab7.0.4. According to the corresponding documentations, PDEPE could be used to solve functions in one space variable and time. If anyone of you have experience in this issue, please give me some examples on solving set of...

    Membrane Impedance

    Hallo Greg Locock, thanks a lot for your reply. It's a pity there is no the recommended book in my library. Actually I'm looking for some formulae on membrane, which are expected to directly relate displacement and tension/stress. A reference equation for circular membrane is found in theory...

    Membrane Impedance

    hallo all, I'm working with calculating the acoustic impedance of a rectangular/square membrane, i.e. Za = acoustic_pressure/volume_velocity. I have been searching the relevant equations, but so far unseccessfully. If you have the formulae on hand or any book to be recommended, kindly give me...

    Transfer Function

    Hallo all, I've calculated a transfer function of my model: Delta_Output(w) f(w) = ------------------- Input(w); If I'd like to get the transfer function of my model: Output(w) f_total(w) = ------------------- , Input(w)...

    VOVLAP or VADD

    Hallo all, In my model there are a couple of adjacent solid structures. In order to keep some irregular areas, I'd like to OVERLAP these structures, instead of ADDing them. However I have doubts about the consequences of this treatment in terms of Modal Analysis. Any suggestion is deeply...
