In the past few decades, extensive research on concrete modeling to predict behavior, crack
propagation, microcrack coalescence by utilizing different approaches (fracture mechanics …

Rigorous characterization of fracture evolution in quasi-brittle materials–such as concrete–
requires computationally intensive and, mostly, complex approaches. However, the …

Despite the versatility in modeling complex crack configurations, phase-field damage
models for fracture usually count only on in-house codes, greatly restricting their potential …

A constitutive model based on the combination of damage mechanics and plasticity is
developed to analyse the failure of concrete structures. The aim is to obtain a model, which …

In this paper, a mesoscale model of concrete is presented, which considers particles, matrix
material and the interfacial transition zone (ITZ) as separate constituents. Particles are …

A meso-scale analysis is performed to determine the fracture process zone of concrete
subjected to uniaxial tension. The meso-structure of concrete is idealised as stiff aggregates …

A regularized gradient-extended damage-plasticity model is discussed which is based on a
micromorphic approach in the spirit of Forest (2009). Damage and plasticity are treated as …

This paper presents a crack model that couples the benefits of the damage mechanics
approach and the extended finite element method (XFEM). A crack-tracking technique is …

This paper presents an isotropic damage model for quasi-brittle materials and demonstrates
its performance in crack propagation analysis for concrete. The suggested damage model is …

This paper describes and validates a new fully three-dimensional smeared crack model to
predict the onset and propagation of ply failure mechanisms in polymer composites …
