Investigation of effect of maximum aggregate size on properties of durability of normal concretes

Constitutive modeling of concrete under tensile loading: damage evolution from 3D microcracks

Elastic modulus of recycled aggregate concrete: a multiscale-multiphase modeling approach

Concrete is a multiscale, multiphase composite material whose elastic properties are challenging to predict, particularly when recycled aggregates are used. The inclusion of recycled aggregates introduces greater heterogeneity due to residual mortar, microcracks, and variable material properties, all of which complicat...

Phase Field Modeling Considering Interfacial Effect for Investigating Corrosion‐Induced Damage in Confined Realistic Multiphase Structures

Rebar corrosion is one of the primary causes of deterioration and reduction in the resistance of reinforced concrete (RC) structures. Previous studies employing phase field modeling for corrosion‐related problems commonly idealize concrete as a brittle, homogeneous material and unconfined structures. Moreover, the ph...

An extended state-based intermediately homogenized peridynamic model for concrete failure analysis considering the ITZ porosity

The interfacial transition zone (ITZ) is inherently a porous region that significantly influences macroscopic mechanical and fracture behaviors of concrete materials. In this study, an extended state-based intermediately homogenized peridynamic model (IH-PD) is proposed for concrete failure analysis considering the ITZ...

Numerical modeling of concrete fracture and size effect using position-based high aspect ratio solid elements

The size effect, defined as the reduction in nominal structural strength with increasing size, is a critical phenomenon in concrete and other quasi-brittle materials, governed by fracture processes such as crack initiation, propagation, and localization within the fracture process zone (FPZ). As the structural size inc...
