Modeling the Behavior of the Fiber Reinforced Concrete by

The damage mechanics allows a detailed modeling of reinforced concrete's degradation phenomenon. The theory of isotropic damage leads to quite satisfactory results in the description of both in the local and the global behavior. It is within the scope of this work to provide a model of damage based on the non-linear mechanical behavior of fiber concrete.

Corrosion Effects on the Durability of Reinforced Concrete

May 04,  · C oncrete is more widely used than any other manmade material and has been a construction staple for centuries. The early use of primarily lime-based concrete by the Egyptians and Greeks dates back to 2000 B.C. In the mid-1800s, steel-reinforced concrete was developed using steel ropes, I-beams, and bars; and prestressed concrete was invented in 1928 by Eugène Freyssinet while

Review of Basalt Fiber-Reinforced Concrete in China

Jun 21,  · Research on three-dimensional, randomly distributed BFRC in China is analyzed and summarized in relative depth in this study. The results indicate that the effect of the fiber component and alkali corrosion temperature on the alkali resistance of BF is significant; the BF has little effect on the compressive strength of the concrete; the tensile and flexural strengths of the composites

Damage Modeling of Metallic Fiber-Reinforced Concrete

Jan 01,  · Considering fiber reinforced concrete as two-phase composite, constitutive behavior laws of plain concrete and sliding metallic fibers are described first and then they are combined according to anisotropic damage theory to predict the mechanical behavior of fiber-reinforced concrete. 2.

3 Reinforcement | Nonconventional Concrete Technologies

In the fracture process of discontinuous-fiber-reinforced concrete (FRC), fibers bridging the cracks can provide resistance to further crack propagation and expansion before being pulled out or stressed to rupture (Figure 3-1). It has been widely shown that such fiber reinforcement can significantly improve the tensile properties of concrete.

1. INTRODUCTION. Steel reinforced concrete (RC) is one of the most widely used structural materials in construction. Nevertheless, it is well known that, under certain environmental conditions the corrosion of steel reinforcement can lead to the deterioration or even to the collapse of structural RC elements, requesting expensive repairing and strengthening.

Numerical Study of Damage Growth in Particulate Composites

Damage description was undertaken at the microlevel using a simplified three-dimensional unit-cell model and an isotropic continuum damage theory. The numerical study examined both him and thick specimens with a short or long edge crack to understand the effects of specimen thickness and crack size on the damage initiation, growth, and saturation.

VUMAT Subroutine: Shear modified Gurson–Tvergaard

What is the GTN damage model? The ductile damage model and Gurson damage model are the two most popular models used in FE simulation to model ductile fracture of metal and polymeric materials. The Gurson-Tvergaard-Needleman (GTN) model is a material plasticity model in which the accumulation of ductile damage is represented by the nucleation, growth, and coalescence of microvoids.
