- The application of the standard viscoplastic model and the SREP approach is illustrated, for the Amodel AXS-1655, in the document available here.
Then, we can also go one step further by starting from properties generated on the neat resin only and then using a DIGIMAT FE (Finite Element) approach to compute the response of the fiber filled polymer by numerically introducing the contribution of the fiber content. The data on the neat resin can consist of measured creep curves but, ideally, a model as the EGP model can be used to model the creep curves of the neat resin starting from shorter term tests (compression tests at different strain rates). Considering the UDEL GF-120 grade, we have been able to implement this method and to compare its performances to the standard viscoplastic model and to the SREP approach.
