“…The inability of one conventional manufacturing (CM) method to manufacture complex or net-shape geometries [14,15] and the limitations associated to conventionally manufacturing IN718 can increase manufacturing steps and time. CM methods often create parts with sacrificial volume that do not contribute to performance and thereby increasing material and energy consumption in applications that require lightweight [14,15]. In this regard, net-shape pressure vessels are possible via combination of CM methods, wrought, casting, forging, cutting, machining, welding, to produce the final part geometry [16][17][18][19].…”

Laser powder bed fusion (L-PBF) is one of the most novel additive manufacturing methods used for a wide range of industrial grade metallic materials. The process can produce end-use metal parts with desirable qualities and mechanical properties. L-PBF however, remains a complicated and expensive manufacturing method. Design for additive manufacturing (DfAM) is a key aspect leveraging the uptake of advantages and possibilities offered by AM in augmenting its competitiveness against conventional manufacturing (CM) methods. Inconel 718 (IN718) is a nickel-based superalloy boasting high temperature strength, good oxidation, and corrosion resistance at elevated temperatures. IN718 is commonly used for high performance applications, such as power and process industry parts, and gas turbine components. High inherent toughness, hardness, work hardening, and low thermal conductivity properties make the material difficult to manufacture through conventional machining methods. The layer-by-layer building of powder metals via L-PBF makes it possible to build different geometrical intricacy. The offered manufacturing flexibility for complex high-end metal structures for variety of applications makes L-PBF an alternative manufacturing method for high performance metals. This study investigates use of DfAM for a small-scale pressure vessel with predefined geometry, dimensions, design space and load condition. The aim is to introduce and exploit contemporary design optimization methods and their feasibility with AM. Structures, such as lattices and stress field driven geometries based on finite element analysis are investigated in this study. The designs are virtually tested under predefined pressure load of 50 bar. All four design options are manufactured on EOS M290 and IN718 powder. The result of the study shows the different optimizations decrease weight and improve material savings without compromising the linear load capacity. Optimized designs could also be made in such a way that it does not increase the manufacturing duration or add additional steps to it.

“…To achieve this, topology optimisation is commonly used in automobile design with biomimetic reference models. In literature, several instances have been identified [13], [45] where the biomimetic topology optimisations were driven for the suspension arms, brake paddles, brake callipers, and uprights, see Figure 4(i) and 4(j). journal.ump.edu.my/ijame ◄ [40], (d) dry tire [38], (e) wet tire [38], (f) narrowed paws of a running cheetah [43], (g) magnified tree frog feet [38], (h) bio-inspired brake disk [44], (i) topology optimised suspension arm [45], (j) lattice optimised break paddle arm [13],…”

Automobile engineering often demands creative and innovative concepts to achieve their performance and efficiency targets. However, the strategies used to create these concepts are evolving with time. Recently, heightened attention has been noticed to using biomimetic concepts in the field of automobile design. The studies that apply biomimicry to automobile design often exhibit improvements in vehicle performance and fuel efficiency. Consequently, biomimetic concepts have extended an opportunity to the automobile industry to generate futuristic designs with advanced technology. However, the innovations and inventions in biology are usually published with more complex terminology that is not convenient for the research community working on automobile engineering. Hence, a notable delay is present in transferring the recent discoveries in biology to engineering researches so that they can develop strategies to mimic them. The purpose of this paper is to provide a brief overview of the biomimetic design approaches that have been and can be used in automobile design. In addition, the paper includes a classification of biomimetic concepts, which reveals the current research interests and highlights the areas with a deficit of research that is required to be addressed extensively in the future.

“…For the above problem, Wang et al (2020) propose a novel bionic design method by the bio-inspired idea of "main-branch and sub-branch" for skeleton structures. The main-branch is obtained by the load path analysis and structural sub-branch is occupied by the fish-bone structure.…”

The existing bionic design methods are based on the similarity theory, but it is difficult to find a bionic prototype with high similarity for the control arm. In this paper, a design method combining load path analysis and biological characteristics is proposed to realize the lightweight of control arm. The load path is used to visualize the load-transferred law in structure and identify the load-bearing performance. Then, the structural improvement suggestions are given and a new control arm with the coupling load of bending moment and pressure is established. Then, the cross-section of wheat-stalk is selected as the cross-section of control arm from four kinds of plants including Bamboo, Wheat-stalk, Juncus, Brazilian Horsetail because of its good bending-resistance and torsion-resistance. The bionic model is designed and the mechanical performance is analyzed and verified by Finite Element Analysis. The results show that the stiffness and strength of the control arm are improved by 65.6% and 22.5% respectively, and its weight is reduced by 32.7%, which show the feasibility and efficiency of the proposed method.
