## Abstract A microstructure‐based model of rubber reinforcement is presented describing filler‐induced stress softening and hysteresis by the breakdown and re‐aggregation of strained filler clusters. An extension of the previously introduced dynamic flocculation model, it considers incomplete defo

The successful application of superplastic constitutive model considering grain growth depends on how well the material parameters are identified. However, it is difficult to obtain satisfactory parameters by using the traditional parameter identification method. The reasons are due to that it is di
