Abstract - Due to the improvement in today’s world,
continuous fiber composite with a resin matrix and can be divided into carbon fiber-reinforced polymer (CFRP), glass fiber reinforced polymer (GFRP), aramid fiber-reinforced polymer (AFRP), basalt fiber-reinforced polymer (BFRP) and so on. The most significant characteristics of FRP are lightweight, high strength, strong resistance to corrosion and fatigue, and strong elastic deformation ability. At the beginning of the twenty-first century, Professor Bank and Gentry investigated the thermoplastic GFRP guardrail and found that it was superior to the traditional steel guardrail in terms of energy absorption in the bending failure process.
increasing demand has been put forth regarding the safety measures in Highway Barriers along with their efficiency towards Price, Material Strengths Etc. This results in the requirement for changing the Barrier’s Material considering its weight ratio. The advent of automobiles that use fewer nonrenewable energy sources, as well as sacrificing the protection of occupants due to the minimized weight of the car, is a key problem for both the vehicle sector and the government. Henceforth, a Car, Mini Bus and Bus is designed with the utilization of Solid Works 2020 software which is a tool for modelling design exploiting FRP material. The car body crash analysis is performed in ANSYS 2022 R2 deploying an ANSYS LS-DYNA module utilizing the FEM approach. We are going to Analysis with Three Vehicles a Car, a Truck and a Heavy Truck which are Specified in Different Weights, Speeds and Angles of Impact on the Barrier. along with that, we are comparing the results of the Material which is used now which is Aluminum Alloy and the FRP Material. Testing is carried out with varying speeds and the analysis of stress generated by crashing; deformation of Safety Barrier is performed.
2. PROBLEM DEFINITION In the current scenario of Highway Crash Barriers, the Government allows the use of Steel Alloys like Aluminum Alloy, Chromium Steel Alloy etc. Here there are two main Possibilities of how Accidents can occur:
Key Words: Car Crash Analysis, Explicit Dynamics, LSDYNA, Finite Element Analysis
1.INTRODUCTION At present, the type of highway bridge guardrails mainly consists of steel guardrails and concrete guardrails. For concrete guardrails, the stiffness of the concrete is particularly large, and the damage to the vehicle during a collision is substantial. Besides, the weight of the concrete guardrail is excessively large, which cannot be used in large-span bridges. Although the collision performance of the steel guardrail is better than that of concrete guardrail, the service life of steel guardrail is relatively short, lasting approximately 15 years under normal weather conditions. In view of the serious environmental deterioration in recent years, particularly the occurrence of acid rain, salt fog, and other weather conditions, the service life of the steel guardrail used in bridges has become even shorter. Studies show that many steel guardrails have been seriously rusted before they reach the design service life, causing a high cost of maintenance and reinforcement. Therefore, a new type of bridge guardrail composed of new materials is necessary to be developed to innovate bridge guardrails. In recent years, the emergence of fiberreinforced polymer (FRP) has expanded the strategies for the innovation of bridge guardrail materials. FRP is a

Impact Factor value: 8.226
CASE - 1: We know that car’s Speed is Nearly 60 to 80 km/h so as the car strikes the barrier will Break and the car can cross the road and strike other cars.
CASE - 2: In Case 2 the car’s Speed can give a strong impact on the barrier, that barrier will not break but the car will get damaged and the Person sitting in that car will be injured or the maximum chance is Death for that person.
3. LITERATURE REVIEW J. Santhakumar et al. [1] [2020], made “Design and crash analysis of car body using FRP materials adopting FEM”, it was published in the International Journal of Innovations in Scientific and Engineering Research (IJISER). This paper is regarding an efficient design and analysis of a car crashing is investigated and a hatchback car designed utilizing solid works 2016 software. The car body crash analysis is performed in ANSYS 16 deploying an explicit dynamic module utilizing the FEM approach. Testing is carried out with varying speeds and the analysis of stress generated by crashing, deformed car body parts as well as strain are performed. Z. Butans et al. [4] [2016], a study on Road Safety Barriers, the Need and Influence on Road Traffic Accidents. This article views an example of a road traffic accident, which is also modelled by the PC-Crash computer program. The given example reflects a road accident
