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

Fracture Mechanics of Reinforced Concrete
The propagation of an element-wide blunt smeared crack band in a finite element mesh is analyzed. The results strongly depend on element size; e.g., a four times reduction in element size causes aExpand

Confinement-Shear Lattice Model for Concrete Damage in Tension and Compression: I. Theory
The mechanical behavior of the mesostructure of concrete is simulated by a three-dimensional lattice connecting the centers of aggregate particles. The model can describe not only tensile crackingExpand

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

EFFECT OF FINITE ELEMENT CHOICE IN BLUNT CRACK BAND ANALYSIS
Abstract The previously developed method of element-wide blunt smeared crack bands, which allows an effective finite element analysis of cracks that are not fixed but propagate and do so in anyExpand
