Postcrack Scaling Relations for Fiber Reinforced Cementitious Composites
Publisher: American Society of Civil Engineers
Abstract: The prepeak and postpeak stress‐displacement relations are derived for the bridging mechanism associated with randomly oriented discontinuous flexible fibers in cement‐based composites. The postcrack strength and fracture ...
Applicability of J-Integral to Tension-Softening Materials
Publisher: American Society of Civil Engineers
Abstract: This brief paper addresses the application of the J-integral to fracture analysis and toughness characterization of quasi-brittle materials, with specific focus on the tension-softening behavior in the fracture process ...
Special Issue on Micromechanical Modelling of Quasi-Brittle Materials Behavior: Introduction
Publisher: The American Society of Mechanical Engineers (ASME)
Interface Property and Apparent Strength of High-Strength Hydrophilic Fiber in Cement Matrix
Publisher: American Society of Civil Engineers
Abstract: This study addresses the characterization of fiber-matrix interfacial properties and the apparent strength of high-strength hydrophilic fibers. Single-fiber pullout bond tests and single-fiber pull-to-rupture strength tests ...
Flexural/Tensile‐Strength Ratio in Engineered Cementitious Composites
Publisher: American Society of Civil Engineers
Abstract: In this paper the flexural behavior of a strain‐hardening engineered cementitious composite (ECC) is studied and compared with that observed in a regular fiber‐reinforced cementitious composite (FRC). Unlike concrete or ...
Flexural Strength of Fiber Cementitious Composites
Publisher: American Society of Civil Engineers
Abstract: An analytical model has been developed for the flexural strength of fiber‐reinforced cement‐based materials. The proposed model adopts the fictitious crack concept to relate the flexural strength of these fiber composites ...

Influence of Supporting Base Characteristics on Shrinkage-Induced Stresses in Concrete Pavements
Publisher: American Society of Civil Engineers
Abstract: This paper presents an analytical model for prediction of shrinkage-induced stresses and displacements in concrete pavements due to the restraint of the supporting base. The model relies upon the interfacial friction stress ...
Effect of Fiber Strength and Fiber-Matrix Interface on Crack Bridging in Cement Composites
Publisher: American Society of Civil Engineers
Abstract: This article proposes a new theory for predicting the crack-bridging performance of random short fibers involved in cementitious composites. The current theoretical model for estimating crack bridging performance of random ...
Inclination Angle Effect of Carbon Fibers in Cementitious Composites
Publisher: American Society of Civil Engineers
Abstract: This paper presents an analytic model, which describes the bridging load and fiber stress developed when an inclined brittle fiber bridges a crack. The coupled effect of fiber bending and axial loading is explicitly accounted ...
