How to simulate 1D stress wave propagation?
Dear All, I am trying to simulate Split-Hopkinson Pressure bar (SHPB). I have designed the incident, transmission bar of Al6061-T6, and sample. I am running simulation using Ansys Explicit Dynamics. In results i am getting SOUNDSPEED for Al 6061 : 6108 m/s. which is due to redial or Poisson's ratio (check another discussion: https://forum.ansys.com/discussion/comment/107401#Comment_107401) . But actual experiment neglects the radial effects considering only 1-D wave propagation.
Now, How can I simulate SHPB setup using only 1-D propagation of stress wave? What type of constraints i need to apply?
