PurposeThis paper aims to propose a new concept of product manufacturing mode which takes physical manufacturing theory as the basic starting point. In this work, the authors intend to systematically define the basic connotation and extension of physical manufacturing, and sort out the typical characteristics of physical manufacturing, in order to propose the general concept of physical manufacturing.Design/methodology/approachHow to study the combination of physics, mathematics, mechanics and other disciplines with the manufacturing disciplines, and how to elevate modern manufacturing science to a new height, has always been a problem for scientists in the field of manufacturing and engineering construction people to deeply think about. Therefore, on the basis of tracing the development of physics and combining the attributes and functions of manufacturing, the authors propose the basic concept of physical manufacturing. On this basis, the authors further clarify the connotation and extension, theoretical basis and technical system of physical manufacturing, reveal the basic problem domain of research and construct the theoretical foundation of physical manufacturing research, which are of great theoretical value and practical significance to adjust and optimize the manufacturing industry structure, improve the quality of manufacturing industry development and promote the green development of manufacturing industry.FindingsThe research on the basic theory and technical system of physical manufacturing will therefore broaden the way of thinking and make a better understanding of manufacturing science and technology, which will promote the development of manufacturing industry to some extent.Originality/valueOn the basis of continuous improvement of the basic theory and conceptual system of physical manufacturing, the physical manufacturing technology will become more and more perfect; physical manufacturing system and intelligent manufacturing system will become the mainstream of next-generation manufacturing system.

PurposeIn order to promote the development of modern manufacturing towards high-precision, high-quality intelligence and precision, this paper puts forward the concept of physical manufacturing and conducts a more in-depth theoretical discussion on its basic connotation and characteristics, based on which the application of physical manufacturing in cutting and autoclave curing molding of composite material is briefly introduced.Design/methodology/approachAs a brand-new manufacturing concept, physical manufacturing determines the optimal process parameters according to multidisciplinary simulations, which emphasizes the physical characteristics about long life and high reliability of the processed products, and makes intelligent adjustment of process parameters according to the changes in the environment and equipment status during manufacturing.FindingsThe concept of physical manufacturing has pioneering significance for the basic research and development of advanced manufacturing technology, which helps to further improve production efficiency, reduce production costs and improve product quality.Originality/valueThe concept of physical manufacturing was first proposed, which emphasizes the analysis, reasoning, perception, and deduction during the manufacturing process, to achieve high-quality processing of products.

PurposeThis paper presents a review concerning the analytical and inverse methods of small punch creep test (SPCT) in order to evaluate the mechanical property of component material at elevated temperature.Design/methodology/approachIn this work, the effects of temperature, specimen size and shape on material properties are mainly discussed using the finite element (FE) method. The analytical approaches including membrane stretching, empirical or semi-empirical solutions that are currently used for data interpretation have been presented.FindingsThe state-of-the-art research progress on the inverse method, such as non-linear optimization program and neutral network, is critically reviewed. The capabilities of the inverse technique, the uniqueness of the solution and future development are discussed.Originality/valueThe state-of-the-art research progress on the inverse method such as non-linear optimization program and neutral network is critically reviewed. The capabilities of the inverse technique, the uniqueness of the solution and future development are discussed.
