Modern turbo-machinery plays a major role in today's technology.                Applications are numerous in the aircraft, compressor, and pump                 industries.  The trend is toward more compact machines with lighter             weight shafts and high speeds.  Vibration analysis becomes                      indispensible as weight grows less.  The transfer matrix method is very         popular for these vibration analyses.  The method assumes that beam             theory can be used to determine rotor span stiffness and that the beam          elements have constant cross-section.  However, modern rotor elements           violate these assumptions, having shell configurations of varying               cross-section.  This project incorporates these configuration effects           into the transfer matrix approach.  This is a fundamental advance in            the vibration analysis tool and will be welcome in the rotor dynamics           industries.
