IMPULSE STRESS WAVE-PROPAGATION IN ELONGATED BODIES - APPARENT DEVIATIONS FROM CIRCUIT REALIZABILITY PRINCIPLES

Of concern is the undistorted propagation of pulse stress waves in lon g thin bodies. The primary signals are arbitrarily sharp pulses projec ted along the x-axis. It will be seen that these pulses travel close t o the speed of sound in unbounded media. Secondary pulses follow repre senting interactive disturbances traveling along the y-axis. But the p rocess brings out certain anomalies in circuit realizability requireme nts. These issues, transmission parameters, and coupling between the v arious signals are studied in detail. The results are supported by exp eriments.
