Optimal multi-material selection for lightweight design of automotive body assembly incorporating recyclability

Joining of dissimilar materials

“…The different properties of the different materials are jointly utilised to achieve the product performance needed. This trend is reported for several industries such as: Automotive [176], Aeronautics [209,276], Clothing [289], Tooling [186], Implants [217], Power generation [131], and Marine application [22]. The mix of new materials will require a systematic approach to material selection: these materials will interact with each other in new ways, and new Emerging trends in manufacturing such as light weighting, increased performance and functionality increases the use of multi-material, hybrid structures and thus the need for joining of dissimilar materials.…”

“…This requires the ability to simultaneously optimize material choice and geometry. Recent developments include proposals for multi-material design procedures [276], and optimal material selection with respect to light weight and recyclability [209]. A commonly known example is the Boeing 787 Dreamliner which uses composite materials as the primary material in the airframe structure, although also includes 20% aluminium, 15% titanium, 10% steel, and 5% other [279].…”

A systematic review of environmentally conscious product design

“…Albinana and Vila [102] draw up a framework for integrated materials and process selection in product conceptual design phase. Sakundarini et al [103] presented a multi-material selection method for lightweight design, which incorporated recyclability for an automotive body assembly. In this category, to solve the MS problem in several following steps will lower the modeling and computing complexity, and provide frameworks for material selection.…”

Topological and Topographical Optimization of Automotive Spring Lower Seat

“…His research focused on crashworthiness, where frontal impact and global bending stiffness are considered for material selection. Sakundarini et al (2013) has also recently performed optimum multi-material selection for lightweight automotive body assembly, with recyclability as one of the design parameters. The price of secondary material was considered during the material selection for car door panel.…”

“…As outlined in preceding works, the current automotive trend is to build lightweight vehicles (Cue et al 2011, Sakundarini et al 2013). Many optimization techniques have been introduced to suit the objective of light weight vehicle.…”
