      Hello all,


      I am currently working dynamic analysis to study performance of motorcycle helmet which uses EPP as a liner. Since most of the research are done using LS-DYNA. I have found limited knowledge to model the material behaviour of EPP in ANSYS Explicit Dynamics. What model is suitable for his analysis and the material data needed for my simulation.

      What is EPP?n

      ArrayA good place to start is https://www.dynalook.com/and search the papers of all the prior LSTC LS-Dyna conferences. There is a nice paper on choosing the appropriate foam material model, though it does not address EPP directly. As far as the material data...do you have access to testing equipment? There is a whole world of materials with respect to EPP (different manufacturers, fillers, etc).nnArrayEPP = Expanded Polypropylene I believe. n
