“…Topology optimisation can facilitate engineers in proposing efficient and novel conceptual design schemes; therefore, it has attracted wide attention in engineering and has become the focus in optimisation recently. Currently, many topology optimisation algorithms have been proposed, such as the SIMP (Solid Isotropic Material with Penalization) method [4,5], homogenisation method [2], level set method [6,7], evolutionary method [8], MMTO (Multi-Material Topology Optimization) method [9], MMC (Moving Morphable Components) method [10], multi-component method [11], multi material method [12,13], and robust optimziation method [14,15]. These topology optimisation algorithms have been successfully applied in many fields, such as hierarchical structures (hierarchical structures are optimal from a structural point of view) [16], mechanics [17], thermotics [18], and acoustics [19].…”

Variable-thickness thin plate structures have been widely employed in many engineering applications, such as the automotive industry, aviation industry and civil structures. In this paper, natural frequency and optimization design of nonlinear variable-thickness rectangular thin plates are performed. For this purpose, theoretical solutions of dimensionless natural frequency of the bidirectional linear variable-thickness thin plates are conducted on the three classical boundaries to verify the correctness of a conducted numerical model. Then the natural frequencies of variable thickness plates with different forms including bidirectional and unidirectional nonlinear were compared. Additionally, the difference in vibration characteristics between the thin plate of variable thickness and the corresponding thin plate of equal mass are compared and analyzed, and the results show that when the middle part of the thin plate is thick, the natural frequency increases by a greater percentage. Finally, a new bidirectional stepped variable-thickness plate is proposed to improve the natural frequency of variable-thickness thin plates. Inspired by the stepped idea, the square and circle division methods are employed to improve the natural frequency of variable thickness thin plates, as the optimal design is carried out. The results show that the nonlinear variable thickness after performing an optimal design could significantly improve the natural frequency of thin plates. The finding provides useful insight into the structural design of variable thickness plates for free vibration.

“…Choosing the right Ceramic materials and making rational use is also a prerequisite for the formation of excellent products [8]. In the product design process, the choice of Ceramic materials is an essential part of the process, and sometimes even the primary link [9]. It affects the structural design, manufacturing, cost, performance, life and product quality and even the production cycle [10].…”

Materials are the material basis for product design, and many products design needs to be achieved through Ceramic materials. Materials are not only the material basis of products, but also the hallmark of social civilization. The choice of Ceramic materials is not only one of the decisive factors for the success of product design, but also the key to the artistic aesthetic of the product. The perfect shape, color and function are important, and the material texture can not be ignored, it will affect the final effect of product design. The application of Ceramic materials in product design is too stylized, which seriously restricts the innovative role of Ceramic materials in product design. It is necessary to re-recognize the design characteristics and functions of Ceramic materials and explore their application methods and means. This paper analyzes the importance and complexity of material selection in product design under the perspective of innovation, and further explores the role of material art creation in product design, summarizes the basic principles and methods of material selection in product design, and hopes to pass scientific Ceramic materials. Choose to optimize the design of your product.
