“…Examples of research efforts that consider the viscoelasticity of the bulk material in asphalt mixtures are presented in various studies (49)(50)(51)(52)(53)(54)(55)(56). More particularly, researchers at the University of Nebraska-Lincoln have incorporated the cohesive zone models into a microstructure computational modeling framework that considers mixture heterogeneity…”

More particularly, Kim et al (2005Kim et al ( , 2006Kim et al ( , 2007 have employed the nonlinear viscoelastic CZ model developed by Allen and his colleagues (Yoon andAllen 1999, Allen andSearcy 2001) to simulate the fracture and damage behavior of asphalt mixtures at intermediate temperatures. In order to predict material-specific and rate-dependent viscoelastic fracture of asphalt media, they performed laboratory tests to obtain the linear viscoelastic properties as well as the nonlinear viscoelastic fracture parameters of the asphalt phase and incorporated those parameters into the FEM model.…”

Cohesive zone (CZ) modeling has been receiving increasing attention from the asphaltic materials and pavement mechanics community as a mechanistic approach to model crack initiation and propagation in materials and structures. The CZ model provides a powerful and efficient tool that can be easily implemented in existing computational methods for brittle, quasi-brittle, and ductile failure as well as interfacial fracture, all of which are frequently observed in asphaltic materials. Accordingly, this paper introduces the CZ modeling approach in the form of a state-of-the-art review addressing the concept of CZ modeling, CZ constitutive relations, their implementation into computational methods, and up-to-date applications of CZ modeling to bituminous mixtures and pavement structures. This paper also includes a brief discussion on the current challenges that researchers face and the future directions to the modeling of fracture in bituminous materials and pavements. CZ modeling is not a topic that can be possibly discussed in a single article; therefore, it should be clearly noted that this review primarily attempts to deliver some of the core aspects of CZ modeling in the area of bituminous composites.

“…Cohesive zone models are well-established tools in classical fracture mechanics developed to remove stress singularities ahead of crack tips. Many researchers [13,14,19,20,[30][31][32][33][34][35][36][37] have attempted to model the constitutive behavior for a cohesive zone in which the tractions are described in terms of the displacement differences across the cohesive zone.…”

The damage evolution function can be directly determined by performing fracture tests as shown in several recent studies [35,39,40]. Alternatively, a phenomenological form of the damage evolution, Eqs.…”

a b s t r a c tMany inelastic solids accumulate numerous cracks before failure due to impact loading, thus rendering any exact solution of the IBVP untenable. It is therefore useful to construct computational models that can accurately predict the evolution of damage during actual impact/dynamic events in order to develop design tools for assessing performance characteristics. This paper presents a computational model for predicting the evolution of cracking in structures subjected to dynamic loading. Fracture is modeled via a nonlinear viscoelastic cohesive zone model. Two example problems are shown: one for model validation through comparison with a one-dimensional analytical solution for dynamic viscoelastic debonding, and the other demonstrates the applicability of the approach to model dynamic fracture propagation in the double cantilever beam test with a viscoelastic cohesive zone.Published by Elsevier Ltd.
