  1. Impact attenuator analysis

  2. Impact attenuator analysis

    I am doing impact attenuator analysis by mat33 material for which i have defined a sample graph (note: the coordinates of stress vs volumetric strain are same as defined in the video) The IA is continuous compressing till the volume goes to zero and then the solver terminates the solving process. Please look over the issue soon as i have to attach this IA on full body crash model. Also after impact it is not bouncing back Thanks and regards, iA_0000.hm iA_0000.out
  3. curve editor in radioss

    Thank you.
  4. curve editor in radioss

    Can I edit it in Radioss itself?
  5. curve editor in radioss

    Hello sir, I am performing honey comb analysis (energy absorbed) in Radioss block,material card as M28 Honey comb. I have generated the curves for material. Number of points are around 500.I have entered incorrect values at many coordinates, i want to edit/change the magnitude of X and Y axis in radioss itself. Please help. Thank you.
  6. Function read error

    hello sir, I am also having this same problem of curves. unknowingly i have assigned multiple y values to same x coordinate. How can I edit the curve points in radioss itself? as the no of points are many i don't want to import it again through excel file. thank you.,
  7. Thermal analysis

    Hello, I am performing a thermal analysis for aluminium pipe with one layer of insulation.So how to give conduction interface in this case between pipe and insulation.Do we consider the gap between them? Thanks
  8. Radioss drop test

    In drop test of mobile is it necessary to give gravity load to mobile,if velocity is given. If gravity load is required then how to give it & proceed for it. Thanks
  9. Drop Test graph(T01)

    I am performing a drop test in which i want Global Energy curves & contact forces graph. I have performed it but the internal vs kinetic energy graph is not getting plotted.As both point (blue & red) are stable. please suggest solution for my mistake.
