Simulation of Crack Propagation in Asphalt Concrete Using an Intrinsic Cohesive Zone Model

  title={Simulation of Crack Propagation in Asphalt Concrete Using an Intrinsic Cohesive Zone Model},
  author={Seong Hyeok Song and Glaucio H. Paulino and William G. Buttlar},
This is a practical paper which consists of investigating fracture behavior in asphalt concrete using an intrinsic cohesive zone model CZM . The separation and traction response along the cohesive zone ahead of a crack tip is governed by an exponential cohesive law specifically tailored to describe cracking in asphalt pavement materials by means of softening associated with the cohesive law. Finite-element implementation of the CZM is accomplished by means of a user subroutine using the user… CONTINUE READING
