Bond behavior in pull-out of a ribbed rebar from concrete with recycled concrete aggregates

open access: yesCase Studies in Construction Materials, 2022
In recent years, there is a worldwide growing interest in using concrete mixes with recycled concrete aggregates (RCA). Reinforced concrete is the composite of concrete and steel rebars, where the rebars provide relatively higher tensile strength and ...

Modified virtual internal bond model based on deformable Voronoi particles

open access: yesTheoretical and Applied Mechanics Letters, 2020
: In last time, the series of virtual internal bond model was proposed for solving rock mechanics problems. In these models, the rock continuum is considered as a structure of discrete particles connected by normal and shear springs (bonds).

Effect of Internal Curing with Superabsorbent Polymers on Bond Behavior of High-Strength Concrete

open access: yesAdvances in Materials Science and Engineering, 2020
High-strength concrete (HSC) is widely used in engineering due to its high strength and durability. However, because of its low water-to-cement ratio, external curing water hardly enters the dense internal structure of HSC so that high self-desiccation ...

Bedding plane-embedded augmented virtual internal bonds for fracture propagation simulation in shale

open access: yesTheoretical and Applied Mechanics Letters, 2021
To effectively simulate the fracture propagation in shale, the bedding plane (BP) effect is incorporated into the augmented virtual internal bond (AVIB) constitutive relation through BP tensor. Comparing the BP-embedded AVIB with the theory of transverse
