ABSTRACT
Nonlinear attenuation of exponentially decaying form behind a shock front with finite amplitude is investigated by means of computer simulation. The exponential pulses with various pulse height, pulse duration, rise-time of shock front and exponentially decaying rate behind the front are made by combination of three parameters. Change of pulse height and duration with propagation are calculated by the simulation for various types of exponential forms. Results obtained are: (1) all exponential forms changed their waveforms to N-wave form; (2) attenuation of exponential form is larger than attenuation of initially triangular waveforms. Comparison with Rudenko's experimental result [1] is made.
