Finite element models of damages occurring in conventional unreinforced, steel-reinforced or fiber reinforced plastics-reinforced concrete specimens are investigated. Results illustrate that the proposed integrated technique is an efficient approach for damage identification of concrete structures. Show more Show less

In , two extremely unusual Model S collisions resulted in underbody damage that led to car fires. These incidents, unfortunately, received more national headlines than the other 200,000 gasoline car fires that happened last year in North America alone. In both cases, the occupants walked away unharmed, thanks to the car's safety features. The onboard computer warned the occupants to exit

May 11,  · When the matrix’s tensile capacity is attained, fibers (subject to their length and bonding attributes) will prevent crack formation and growth by efficiently bridging the macro-cracks. Therefore, this is the principal reinforcement mechanism employed in fiber reinforced concrete composites (Banthia 2007, p.2). Fiber-reinforced concrete model

Successful use of carbon fiber reinforced polymer (CFRP) tendons in prestressed concrete bridges can be achieved by combining bonded internal tendons with unbonded externally draped tendons. To examine this theory, four bridge models were tested under static, repeated (7 million cycles), and ultimate loads.

In this study, a peridynamic fiber-reinforced concrete model is developed based on the bond-based peridynamic model with rotation effect (BBPDR).

Garboczi et al. [17] developed an algorithm to generate realistic shapes of different aggregate particles.On the other hand, various material models for the aggregate and the mortar have been employed to study the concrete behaviour, for example, 2D linear elastic analysis [18], nonlinear orthotropic fracture model [14] and isotropic damage

For fiber-reinforced epoxy layers, the primary model considered is based on the built-in damage model for fiber-reinforced composites available in both Abaqus/Standard and Abaqus/Explicit.Alternatively, in Abaqus/Standard, the damage in the fiber-reinforced epoxy is also simulated using the model proposed by Linde et al. (2004), which is implemented in user subroutine UMAT and is discussed below.

Patnaik et al. ). There are many different metallic and non-metallic micro or macro fiber available for use in fiber reinforced concrete. A new type of macro fiber known as MiniBars was recently made from basalt fiber and is gaining acceptance in the industry. The addition of fiber to concrete will also improve the bond strength between the

The system has a trapezoidal configuration that offers an easy on-site installation and uninstallation procedures without residual damage on the metallic beam. Three 5-m-long steel beams were statically tested until failure, including one reference unstrengthened beam and two beams that were strengthened with 15% and 31% CFRP prestress levels.
