“…Traditional FEM is not appropriate for solving fracture problems in heterogeneous materials due to the large amount of re-meshing work. CZM has received increasing attention from pavement technologists and asphalt researchers over the past few decades, as it can model both brittle failure and ductile failure, which are commonly observed defects in asphalt materials due to the wide range of service temperatures and loading rates [82,83]. CZM can predict the damage evolution in the fracture process zone located ahead of a crack tip.…”

Modeling is an important approach for describing the physical and mechanical properties of asphalt, which can be employed to analyze the properties and optimize the performance of asphalt-based materials. The objective of this review is to elucidate the existing modeling techniques from different scales and summarize the prospects and application of different modeling methods. The continuum model and its practical application at the macroscale are introduced first. However, the macroscopic model cannot explain the roles of the different components in asphalt during the degradation process. The microstructural model at the mesoscale is adopted in order to describe the physical properties of the asphalt mixture, and different numerical methods are presented in order to analyze the microstructural models. Due to the heterogeneous nature of asphalt at the nanoscale, various experimental tools have been used to determine the molecular structures of asphalt. The average model and multi-component model have been proposed in the molecular dynamics simulations. This paper provides a clear understanding of the strength and limitations of each modeling technology at different scales and the applications of multiscale modeling for asphalt materials. The possible challenges of asphalt modeling have been addressed in order to encourage the development of asphalt pavement with higher durability.

“…Rocha et al [177] and Sousa et al [178] investigated Mixed Mode fatigue fracture behavior for different adhesive systems and studied the effects of mode mixity. Concerning joining of dissimilar materials, Choi and Kim [179] studied the fatigue crack growth specimens with straight and penny-shaped cracks. Indicative results from the application of the CZM method to predict fatigue crack growth in the CLS specimen are given in Figure 13.…”

In the framework of the Cost Action CERTBOND (Reliable roadmap for certification of bonded primary structures), a wide group of researchers from 27 European Countries have had the opportunity to work on the topic of certification of bonded joints for primary structural applications from different engineering sectors such as the aerospace, automotive, civil engineering, wind energy and marine sectors. Since virtual testing and optimization are basic tools in the certification process, one of the key objectives of CERTBOND is to critically review some of the available models and failure theories for adhesive joints. The present paper summarizes the outcome of this task. Nine different models/theories are described in detail. Specifically, reviewed are the Classical Analytical Methods, the Process Zone Methods, Linear Elastic Fracture Mechanics (LEFM), the Virtual Crack Closure Technique (VCCT), the Stress Singularity Approach, Finite Fracture Mechanics (FFM), the Cohesive Zone Method (CZM), the Progressive Damage Modeling method and the Probabilistic methods. Also, at the end of the paper, the modeling of temperature effects on adhesive joints have been addressed. For each model/theory, information on the methodology, the required input, the main results, the advantages and disadvantages and the applications are given.

We present a stabilized finite element method for thermomechanical problems in the class of materials with discrete microstructural interfaces that undergo interfacial fatigue and dominant interfacial damage. This formulation is applicable to polycrystalline solids, fibrous composites, filled elastomers, and additively manufactured layered materials. A finite strain formulation for monolithically coupled thermomechanical fields is presented where interfacial kinematic models for low-cycle fatigue and for strong interfacial discontinuities are variationally embedded at the interfaces. Formulation is written in the spatial configuration to account for large local strains and finite rotations of the interfaces. The method is implemented employing the family of low-order 3D Lagrange elements comprised of linear hexahedra and linear tetrahedra. A set of benchmark problems is presented to show the mathematical and algorithmic attributes of the method.
