Optimizing Material Selection for Automotive Fenders Using the WASPAS Method A Life Cycle Engineering Approach

Materials selection constitutes a multidisciplinary activity that involves a wide range of knowledge subjects and professional domains. In reality, a material selection choice should include additional considerations than just the functional performance necessary for the application, but also the economic and environmental implications that arise during the product's life cycle. An approach known as life cycle engineering (LCE) strategy is provided in this study to enhance material selection by combining its suitability on behalf of the specific application according to technological, environmental, and economic aspects throughout the product's lifespan. The suggested technique examines a range concerning candidate materials and determines the ''best material domains'' by aggregating the three characteristics (technical, economical, and environmental). These ''best material domains'' are displayed beneath a ternary diagram, allowing for a worldwide inquiry into candidate materials and assisting in making an educated decision on the selection of the ''best material'' based on various business circumstances and corporate strategy. The technique was used to a case study aimed at the usage of freshly developed metal objects (high strength steels while participating aluminum alloys) for a vehicle fender that is constructed of mild steel, as well as the evaluation of possible benefits in terms of the material's overall performance. Transportation fenders are an important section of a vehicle's outer body that hedges the wheel arches traveler’s road debris, water, in addition to other factors. They are subjected to a variety of mechanical and environmental stressors, including as impact, abrasion, corrosion, followed by temperature variations. As a result, choosing the right materials for car fenders is critical to ensuring their longevity, performance, additionally aesthetic appeal. Materials for car fenders are chosen based on a number of considerations, notably cost, performance, fabrication, and aesthetic needs. Automotive manufacturers frequently undergo thorough testing and analysis to verify that the materials used match the unique needs of their cars as well as consumer expectations. The selection of materials for vehicle fenders is an important component that live in automotive design and development. Fenders are essential regarding protecting your vehicle's body particularly components throughout highways debris, water, and various additional outside factors. As a result, the materials used for fenders have a substantial influence on the performance in general, durability, safety, together with aesthetics of cars. The substrate selection for car fenders is a significant component in automobile engineering and development. Fenders are vital for protecting your vehicle's the entire body, most especially components along roads from trash, water, and other outside influences. consequently, a result, whatever materials are chosen for flaps have a significant impact on the performance, overall durability, safety, and aesthetics of automobiles. In this research we will be using Weighted Aggregates Sum Product Assessment (WASPAS). Alternative Parameters taken as D600D, D1000DP,AA2036T4,AA 6010T4, PPE/PA/989, PPO/PA66, NY66/40CF, PPS/40CF, AR/PC, PC/PBT. Evaluation Parameters taken as Specific Heat Capacity (J/kg°C), Ultimate Tensile Strength (MPa), Yield Strength (MPa), Linear Coefficient of Thermal Expansion (µm/m-°C), Density (g/cc), Material Cost ($/kg). Result: As per Weighted Aggregates Sum Product Assessment (WASPAS) D1000DP got more value were AA6010T4 got less value. From the above results I conclude that as per Weighted Aggregates Sum Product Assessment (WASPAS) we get to know that D1000DP got more value than others.
