“…The bolts used in the crash test connected the joint between two segments. This connection was also included in the theoretical model, and the simulated results using LS-DYNA software were compatible with the crash test results, as demonstrated by Consolazio et al (2003). Marzougui et al (2003) modified the connections between the portable concrete barriers.…”

“…Two sets of two loops were connected between the adjacent barriers. Consolazio et al (2003) modified concrete barriers that were 508 mm in height, 6.1 m in length, and 49 kN in weight. Zhao et al (2004) tested a concrete barrier 810 mm high above the surface of the road.…”

“…However, the collision angle of the first car was 20° and that of the second car was 25°. Consolazio et al (2003) conducted a full-scale crash test using two types of vehicles (a 2000 P and an 820 C), simulated both cars, and then compared the experimental and simulation results. Bullard in (2003a) tested two aesthetic bridge rails, one concrete barrier, and one steel barrier using a pickup car.…”

“…Vehicles that cross into the opposite lane may cause serious traffic accidents; therefore, concrete barriers must be able to prevent such vehicles from entering the opposite lane to prevent occupant injury and vehicle destruction, Se-Jin et al (2008). Experimental impact tests have been established in several studies that have used full-scale vehicle tests to test the ability of concrete barriers to withstand impact loads exerted on them by collisions with vehicle, Consolazio et al (2003) and Bambach et al (2010). Laboratory models have been used in other studies to test impact loads, Gabauer et al (2010).…”

“…Laboratory models have been used in other studies to test impact loads, Gabauer et al (2010). Theoretical finite element method (FEM) is used by several software, in particular LS-DYNA and ANSYS programs, to simulate concrete barriers and vehicles, Itoh et al (2007a); Se-Jin et al (2008); Consolazio et al (2003); Borovinšek et al (2007); Zhong et al (2009) ;Wang et al (2013). One of the most critical road transportation problems is the protection of road users.…”

Concrete barriers prevent vehicles from entering the opposite lane and going off the road. An important factor in the design of concrete barriers is impact load, which a vehicle exerts upon collision with a concrete barrier. This study suggests that a height of 813 mm, a base width of 600 mm, and a top width of 240 mm are optimum dimensions for a concrete barrier. These dimensions ensure the stability of concrete barriers during vehicle collisions. An analytical and experimental model is used to analyze the concrete barrier design. The LS-DYNA software is utilized to create the analytical models because it can effectively simulate vehicle impact on concrete barriers. Field tests are conducted with a vehicle, whereas laboratory tests are conducted with machines that simulate collisions. Full-scale tests allow the actual simulation of vehicle collisions with concrete barriers. In the vehicle tests, a collision angle of 25°, collision speeds of 100 km per hour, and a vehicle weighing more than 2 t are considered in the reviewed studies. Laboratory tests are performed to test bridge concrete barriers in static condition.

The seagull feather shaft is an important part of the feather, which provides a good mechanical support for the excellent flight performance of seagull, and has the characteristics of lightweight and high strength. In this paper, the microstructure of the seagull feather rachis was observed firstly. Then, based on the structure of feather rachis, combined with the cortex that plays the main load-bearing role, a model with the characteristics of the cortex was proposed and its finite element model was established. Through analyzing the simulation, the effect of section shape of cortex on mechanical properties of feathers under axial impact was revealed. And the conclusion that the section shape with groove structure and non-equal wall thickness could have different effects on mechanical properties was drawn. Then, parameterized cortical models were studied, including different impact velocities and different cortical heights, to reveal the differences in mechanical properties of cortical models.
