Erosion Wear Estimation Simulation Result Vs Experimental Result

      I have created a solid particle erosion wear model in explicit dynamics  to estimate the mass loss of the plate due to multiple ball impact on the plate. 


      In the user defined result I used Expression = Erosion and get some results. I have also exported results in excel file and values indicated as 0, 1 and in some cases 0 and 2. 


      I am unable to understand the meaning of these values.


      I have to compare the simulation result and experimental result for wear. 


      Please guide me about the same.


      Screen shot and result file is attached here

      Hi,


      Erosion=0 means not eroded, Erosion >0 means eroded

      Thank you sir


      After knowing the eroded elements my interest is to know the volume of the single element. How can I calculate the volume of single element ??


      Thanking You

      @manvendrayadav  Wear and element erosion are normally quite different in terms of amount of material removal.  If you want to actually wear, then you may want to investigate either a time transient solution with the Mechanical APDL solver (Mechanical is the pre/post processor).  Wear can be added to a contact pair.  Or if the model is best solved with an explicit code then Workbench LS-Dyna can also include wear.

      @mrife Thank You !!


      My interest is to estimate the loss of material of a plate due to the impact of several impact of the particles. 


      With Regards
