The work is concerned with the application of a new tool computer graphics rather than the development of a new analytical technique. The problem of the dynamic response of a nonuniform beam was treated using the currently standard techniques of lumped mass-spring representation of the structure. A graphic input and output capability was attached to standard digital computer programs so that one can display on the face of a cathode ray tube the input parameters, modify these if desired, and then compute the modal behavior of the beam. The engineer can return to the initial input data, make changes, and rerun the program if he so desires. For the forced response problem, he can input his forcing functions, compute the forced response, and present the results in an animated display. This technique for communicating with the computer gives immediate reduction and interpretation of the results from the forced response program, a task which in the digital form requires many hours or even days.
