a r t i c l e i n f o Keywords: Concrete (E) Fiber reinforced concrete (FRC) (E) Constitutive relationship (C) Cohesive fracture (C) Fracture energy (C) A simple, effective, and practical constitutive model for cohesive fracture of fiber reinforced concrete is proposed by differentiating the aggregate bridging zone and the fiber bridging zone. The aggregate bridging zone is related to the total...

Abstract The use of fibers, especially natural as construction materials has begun to develop. Natural fibers are also used for soil stabilization, where there two mechanisms increasing strength: tensile strength and fiber-soil friction. purpose this research is design build simple, inexpensive tools that can be test the a fiber. tool consists three main parts, namely pull tool, loadcell, displ...

Cell contractility is mainly imagined as a force dipole-like interaction based on actin stress fibers that pull cellular adhesion sites. Here, we present different type of isotropic contractions within the actomyosin cortex. Measuring mechanosensitive cortical suspended cells among various cell lines allowed us to exclude effects caused by fibers. We found epithelial display higher tension than...

A theoretical model of a single piezoelectric fibre pull-out is developed to study the interaction between fibre deformation, pull-out stress and corresponding electrical field. Computer simulation of the stress–displacement curve of the fibre pull-out process is presented. Numerical examples show that the piezoelectric fibre pull-out behaviour can be both described and affected by its electric...

This paper is on modeling and measuring fiber-bridging constitutive law of Engineered Cementitious Composites (ECC), a high performance fiber-reinforced cementitious composite featuring high tensile ductility. Fiber-bridging constitutive law plays an important role in the multiple cracking behavior of ECC. Therefore, proper control of fiberbridging behavior through tailoring material microstruc...

in most cases, fiber reinforced self-compacting concrete (frscc) contains only one type of fiber. the use of two or more types of fibers in a suitable combination may potentially not only improve the overal properties of self-compacting concrete, but may also result in performance synergie. the combining of fibers, often called hybridization, is investigated in this paper for a cimentetious mat...
