Abstract:

Computer analysis, a direct numerical method for analyzing stress wave propagation in solid bodies, is described and applied to a group of dynamic problems. This method incorporates the governing physical laws directly into computer programs to product dynamic changes occurring in a system, thus completely bypassing the differential equations to reach the final results. Propagation schemes and sample programs are presented for problems of elastic and plastic wave propagation in a thin bar and in a sphere. The method is quite general and can be extended to many other dynamic problems. Author
