Extreme Dynamic Tension Theory: Preliminary Research

The dynamic tension fracture has brought much interests in various engineering applications ranging from the pressure vessel/pipe failure to the explosively driven fragmentations in the commercial/space or military applications. There has been great improvement in this area of study by many researchers, but the question regarding the fundamental mechanism of extreme tension remains unanswered. In this report, an extreme dynamic tension theory based on the conservation equations is proposed, and it is evaluated by a series of MD (molecular dynamic) and hydrocode simulations. In-depth descriptions of tension wave speed, wave profile, tension pressure/profile, particle velocity of the plastic tension wave, etc. are present, hoping to provide a clue to understand the extreme dynamic tension physics prior to the crack formation.
