STRESS PULSE-TRAINS FROM MULTIPLE REFLECTION AT A ZONE OF MANY DISCONTINUITIES A NOTATION FOR MACHINE SOLUTION

摘要

Presented in this report is a numerical method by which may be calculated the amplitudes of the trains of pulses that result when a single simple stress pulse encounters a zone of many abrupt discontinuities in a slender rod. The notational scheme employed enables the system of multitudes of individual progagating waves to be studied in terms of analo¬gous number sets which may be mechanically generated. The notational concept and related operational rules, described in this report, have been used to program the problem for solution with the IBM 704 Computer. The program is briefly discussed.
