In this study, the nature of 2D extreme dynamic necking will be investigated using the 1D extreme tension theory with the use of a series MD (molecular dynamic) code simulation. In more specifically, the particle behavior and the wave propagation pattern will be analyzed in order to understand the particle kinetics, thermodynamics, and mapping of the pressure profile during the extreme dynamic necking event (pull speed is in the range of several km/s). This study is aiming to reveal the materials property mapping prior to the crack formation.
