Continuum damage finite element modeling of asphalt concrete
This paper presents the research into the implementation of the viscoelastic continuum damage model (VCDM) of asphalt concrete into a finite element analysis. The VCDM is based on: (1) the elastic-viscoelastic correspondence principle using pseudostrains; (2) the work potential theory for damage modeling; and (3) the time-temperature superposition principle with growing damage. With the aid of Schapery's preceding work, the VCDM is implemented in a three-dimensional setting. The resulting material model was implemented in the commercially available finite element program, ABAQUS. Results from constant crosshead rate monotonic tension tests at varying temperatures and strain rates were used to verify the finite element model. Verification results are promising when the viscoelastic response dominates the behavior. However, at high temperatures and/or slow strain rates, the effect of the viscoplastic response in the mixture was found to be important and warrants the incorporation of the viscoplastic model for an accurate response prediction.
