Lattice Discrete Particle Model (LDPM) for failure behavior of concrete. II: Calibration and validation
Abstract The Lattice Discrete Particle Model (LDPM) formulated in the preceding Part I of this study is calibrated and validated in the present Part II. Calibration and validation is performed byExpand
Two-scale Study of Concrete Fracturing Behavior
The cohesive crack model is, nowadays, widely used for the analysis of propagating cracks in concrete and other quasi-brittle materials. So far the softening curve, which gives the stress transmittedExpand
Lattice Discrete Particle Model (LDPM) for failure behavior of concrete. I: Theory
Abstract This paper deals with the formulation, calibration, and validation of the Lattice Discrete Particle Model (LDPM) suitable for the simulation of the failure behavior of concrete. LDPMExpand
Cohesive crack analysis of size effect
Abstract This paper deals with the analysis of size effect in concrete. An extensive campaign of accurate numerical simulations, based on the cohesive crack model, is performed to compute the sizeExpand
CONFINEMENT-SHEAR LATTICE MODEL FOR CONCRETE DAMAGE IN TENSION AND COMPRESSION: II. COMPUTATION AND VALIDATION
The concrete material model developed in the preceding Part I of this study is formulated numerically. The new model is then verified by comparisons with experimental data for compressive and tensileExpand
Strain-rate effects on concrete behavior
Abstract In this paper, a previously developed meso-scale model for concrete, called the Confinement Shear Lattice (CSL) model, is extended in order to include the effect of loading rate on concreteExpand
Hygro-thermo-chemical modeling of high-performance concrete. II: Numerical implementation, calibration, and validation
This paper presents the numerical implementation, calibration, and validation of the hygro-thermo-chemical model formulated theoretically in the companion paper [Di Luzio G, Cusatis G.Expand
Temperature Effect on Concrete Creep Modeled by Microprestress-Solidification Theory
The previously developed microprestress-solidification theory for concrete creep and shrinkage is generalized for the effect of temperature ~not exceeding 100°C!. The solidification model separatesExpand
Confinement-shear lattice CSL model for fracture propagation in concrete
Abstract A previously developed lattice model is improved and then applied to simulations of mixed-mode crack propagation in concrete. The concrete meso-structure is simulated by a three-dimensionalExpand
Solidification–microprestress–microplane (SMM) theory for concrete at early age: Theory, validation and application
Abstract This paper presents a new constitutive model describing the mechanical behavior of concrete at early age and beyond. This model, entitled solidification–microprestress–microplane (SMM)Expand
