The Impact

The Gleeble3500 combined with SEM, TEM and other experimental methods are employed in this paper to investigate the effects of zirconium content on impact toughness of heat affected zone (HAZ) of hull structure steel plate during the large heat input welding. The results showed when 0.01% zirconium were added in the steel, the impact energy reached 224 J at-60°C experienced 150 kJ/cm welding heat input. But the large-size rectangular inclusions are found in CGHAZ when 0.02% zirconium were added in the steel, the impact energy fell to 38 J at-60°C experienced 150 kJ/cm welding heat input, the large-size inclusions, especially rectangular inclusion, were the main cause for the sharp decline of low temperature toughness after welding.

The Impact

Various welding methods are widely applied in large fabrication of high strength steel. However, commonly the problem occurs where a coarse grain is formed near fusion zone causing reduce the impact toughness due to the weld joint become brittle. Ductility and toughness in a coarse grain heat affected zone (CGHAZ) is low due to the formation of coarsening grain size. The objective of this research is to investigate the microstructure evolution, impact toughness and fracture appearance at sub-zero temperatures of the high strength steel arc welded. The steel that used in this experiment is a HY-80 steel welded by gas metal arc welding (GMAW) with a mixture of argon and carbon dioxide (90%Ar and 10%CO2) and ER100S solid wire. Microstructure observation and Charpy V-notch (CVN) tests were performed on the weld joint which consist of base metal (BM), heat affected zone (HAZ), and weld metal (WM). The CVN tests on the HY-80 steel plate at various temperatures (20, -20, -60 and -80 °C) show impact toughness decrease when the test temperature decrease. The CVN tests on the HY-80 weld joint at a temperature of 80 °C show the lowest impact toughness was measured at WM (61 J) and followed fusion line-FL (101 J) with brittle fracture appearance.

The study of Dong ethnic cultural resources provides the experience basis and method path for the designing and development of cultural and creative products with Dong ethnic-cultural characteristics. In the research, first of all, the Dong culture is mainly taken as the core and the Dong cultural resources are classified. Secondly, it studies the attributes of cultural and creative products and designs and combs the cultural and creative products of Dong nationality. Furthermore, the creative product design model of Dong ethnic culture is constructed, and eye tracking technology is taken as an example to accurately extract the cultural identification characteristics of cultural materials through modern science and technology, and the specific case design is carried out. Through the excavation, arrangement, and induction of Dong ethnic cultural resources, the attributes of cultural and creative products are analyzed, and the design model is constructed to provide ideas for the design of Dong ethnic cultural and creative products, which is conducive to enhancing the value of Dong ethnic culture and cultural and creative products and provides references for the cultural development of other ethnic minorities.

The Impact

Today, product design process is facing a market globalisation led by distributed teams. The international market context, in which industrial companies evolve, leads design teams to work in a large multidisciplinary collaborative context using collaborative practices. In this context, product design process is driven by the integration and optimisation of stakeholders’ collaboration. Thus, to facilitate collaborative steps, new management strategies are defined and new information systems can be used. To this end, we have focused our article on the topic of collaborative product design project management. We have underlined the necessity to use quantitative and non-intrusive indicators during the management of collaborative design phases besides subjective evaluations. Tracking these indicators is performed in parallel to the existing approaches in order to evaluate the performance of collaborative design project. Moreover, these indicators can show the impact of the collaboration steps on the design project evolution. The computation of proposed indicators is based on precise metrics which details the completeness of the computer-aided design model and its evolution depending on the used collaborative tools and the project milestones. This computation uses the importance of each computer-aided design model part and the transformation rate of each part of the computer-aided design model.

The Impact

This paper proposes a conceptual model to support sustainable product design. The approach develops an integrated multimodal decision making model which is to be introduced early in the design process, as the basis for the integration of the life cycle assessment into an Eco-design model. The model, which is based upon an adapted “House of Quality” analysis, supports designers when assessing the environmental impact of the product design. The resulting Eco-design model evaluates the sustainability of the designed product using criteria that consider the impact of manufacturing process, product usage and end-of-life (EoL) disposal strategy. This approach is demonstrated using a case study that considers the design of a set of crocodile medical forceps, in which the redesign of a new forceps is undertaken by considering all the parameters in the Eco-design model.

Maslow’S Hierarchy Of Needs

Based on the analysis of Maslow’s hierarchy of needs, this study explored the method of product design which takes five levels of human needs as a starting point. By combining with the dual attributes of modern Chinese furniture on industrial product and cultural product, this research proposed a design model of modern Chinese furniture based on hierarchy of needs, which can provide with cross-references to design practice.
